What happens if EPI is left untreated in dogs?
When EPI is undiagnosed and left untreated, the entire body is deprived of the nutrients needed for growth, renewal, and maintenance. In time, the body becomes so compromised that the dog either starves to death or dies of inevitable organ failure.
Can You give Dogs with EPI without enzymes?
Once an EPI dog is stable, some owners find that they can “cheat” and give their dog a smidgeon of a treat without any enzymes on it. Others find the least little crumb ingested without enzymes will cause a flare-up.
How old do dogs have to be to get epi?
EPI can occur in dogs of any age, but signs are usually first seen between six months and six years of age (Hall et al., 2003).
Can epi dogs tolerate more than 12 percent fat?
This may explain why some EPI dogs can tolerate higher concentrations of fat. For those dogs who cannot tolerate more than 12 percent fat, this may mean that the fat content needs to be increased very gradually, or perhaps that certain types of fat may be tolerated better than others. Much more research is needed to answer these questions.

Can a dog survive with EPI?
A dog diagnosed with EPI will require lifelong management. With appropriate management, dogs can live normal lives and have a normal life expectancy. Once EPI is diagnosed it can be easily managed with the addition of digestive enzymes to meals.
How Long Can dogs live with EPI?
EPI dogs can continue to live a full life and do all the activities they did before, EPI, in and of itself, when treated , does not shorten a dog's lifespan, The key is successful management. Pictured to the left is Maia. Maia, now 7 1/2 years old, was diagnosed with EPI when she was about a year old.
Does EPI cause pain in dogs?
Without proper treatment, the EPI dog can suffer greatly and even die a painful death from malnourishment, starvation or organ failure. With EPI, organs, the immune system, nervous system and all other body systems may become compromised to one degree or another.
Is EPI in dogs fatal?
Once the pancreas is damaged to the point that symptoms of EPI develop, you will need to give your dog pancreatic enzyme supplements and possibly other treatments for the rest of their life. However, with proper management, your dog can live a healthy and happy life.
What happens if EPI is not treated in dogs?
(2) Exocrine cells produce and secrete digestive enzymes. When EPI is undiagnosed and left untreated, the entire body is deprived of the nutrients needed for growth, renewal, and maintenance. In time, the body becomes so compromised that the dog either starves to death or dies of inevitable organ failure.
How Long Can dogs live with pancreatic insufficiency?
Nineteen percent of treated dogs were euthanized within 1 year, but overall median survival time for treated dogs was 1919 days.
How do you comfort a dog with pancreatitis?

Is pumpkin good for dogs with EPI?
1/2 to 1 teaspoon of canned pumpkin is usually good to add to the food for EPI dogs, especially if the grain free does not seem to be working as well as you think it should… it might mean that your dog needs a little bit of the right kind of fiber and pumpkin is a good fiber to start with.
How much does it cost to treat a dog with EPI?
$150 to $300Cost of Pancreatic Enzyme Replacement in Dogs The initial cost of tests and diagnosis of EPI can cost $150 to $300. The cost of pancreatic enzyme replacement therapy varies widely depending on the dosage required. For large dogs requiring significantly more enzyme replacement, costs are greater.
How do you treat EPI in dogs naturally?
Probiotics are an important aspect of managing your dog's EPI and helping balance her gut bacteria. Feed your dog probiotic-rich foods like fermented veggies or give high quality probiotic and prebiotic supplements. Prebiotics help feed probiotics and make them more effective.
What do you feed a dog with exocrine pancreatic insufficiency?
For some, a very high-protein, grain-free food is the right choice, while other dogs with exocrine pancreatic insufficiency actually need some grain, with its attendant fiber. Complicating the issue further is that there are two kinds of dietary fiber, soluble and insoluble.
At what age do dogs get EPI?
EPI can occur in dogs of any age, but signs are usually first seen between six months and six years of age (Hall et al., 2003).
What Is EPI in Dogs?
EPI stands for exocrine pancreatic insufficiency. EPI in dogs is a health issue that has serious effects on the pancreas. It happens when most of the cells that produce digestive hormones don’t function normally.
What is the best treatment for EPI in dogs?
Dogs with EPI are usually managed at home with pancreatic enzyme supplementation and cobalamin supplementation. Some dogs also require additional vitamin supplements, antibiotics, medications to reduce the secretion of stomach acid, and other treatments to manage their symptoms.
What test can be done for exocrine pancreatic insufficiency?
Diagnosis. If symptoms of exocrine pancreatic insufficiency are apparent, a number of pancreatic function tests can be done. A serum sample that measures the amount of the chemical trypsinogen (TLI) released into the blood from the pancreas should reveal problems in the pancreas. A dog with EPI will have reduced amounts of TLI.
What happens if a dog's pancreas fails to produce enough enzymes?
If the pancreas fails to produce enough of these digestive enzymes, exocrine pancreatic insufficiency, or EPI, develops. EPI may affect a dog's gastrointestinal system, as well as general nutrition, and can cause problems such as weight loss and chronic diarrhea.
Why does my dog have EPI?
Causes. The most common cause of EPI in dogs is idiopathic pancreatic acinar atrophy (PAA). The enzymes responsible for aiding the digestion of starches , fats , and proteins , are produced by cells in the pancreas known as pancreatic acinar cells. PAA develops when these cells fail to function properly, thereby leading to EPI.
Why is PAA so common in dogs?
PAA appears to be an autoimmune disease, meaning that a dog’s own immune system attacks and destroys the pancreatic cells responsible for producing digestive enzymes. The primary risk factor for PAA in dogs is genetic, which is why EPI is seen more frequently in certain breeds of dogs.
How to treat EPI in dogs?
Treatment. Once EPI has been diagnosed, treatment most commonly consists of supplementing your dog's diet with a pancreatic enzyme replacement. These enzyme supplements come in a powdered form which may be mixed with food. Also, if your dog is undernourished, vitamin supplements may be necessary.
What Is Malabsorption In Dogs?
The Merck Veterinary Manual defines malabsorption as “the defective uptake of a dietary constituent resulting from interference with its digestion or absorption…” This is usually caused by a small intestinal disease that interferes with the digestive processes.
How does the immune system work in dogs with leaky gut?
And the immune system is activated to fight the intruders. The body’s systems can get overwhelmed, resulting in inflammation … but as the immune system attacks these intruders, it can also lead to allergies and other chronic disease, including the potential for autoimmune disease. Because these invaders include undigested food particles, the body starts to treat food as its enemy – so dogs with leaky gut often have multiple allergies to many different proteins as well as vegetables and grains.
What causes a dog to be malabsorption?
Inflammatory bowel disease, mucosal damage. Villous atrophy (villi are microscopic cells that line the small intestine; they can become damaged through inflammation, leading to leaky gut syndrome) Let’s focus on 3 important disease conditions that could cause malabsorption in your dog. 1.
What is the term for the failure to absorb a dietary constituent?
The Merck Veterinary Manual defines malabsorption as “the defective uptake of a dietary constituent resulting from interference with its digestion or absorption…” This is usually caused by a small intestinal disease that interferes with the digestive processes.
What is the term for an imbalance of bacteria in the microbiome?
Dysbiosis is an imbalance of bacteria in the microbiome (the community of microbes in the body), with too many bad bacteria and not enough good bacteria. The bacteria in the microbiome help digest food, regulate the immune system, protect against other bacteria that cause disease, and produce vitamins including B and K and other essential nutrients.
How to treat EPI in dogs?
EPI is treated (even in conventional medicine) using pancreatic enzymes to compensate for your dog’s own lacking enzyme production. Porcine enzymes in a powder given with food are considered the best. If your dog doesn’t tolerate pork well, there are also beef-based or plant enzymes. The powder must be “incubated,” which means you add it to your dog’s food moisten the powder, and let it sit at room temperature for 20 to 60 minutes before feeding. Otherwise the enzymes can cause mouth bleeding or sores. If that happens, reducing the dose usually resolves the problem.
Why is my dog not eating enough food?
EPI And Other Digestive Diseases In Dogs. There are several conditions that can cause your dog not to absorb nutrients properly from her food. When that happens, it’s called malabsorption. And it’s a serious problem. Food is what gives your dog a foundation of good health.
What is the best treatment for EPI in dogs?
Management of EPI cases revolves largely around supplementation with pancreatic enzymes, which can be provided in numerous forms including tablets, capsules, granules, uncoated enzyme powder and raw pancreas. There has been considerable debate about efficacy of such products, with earlier work suggesting that dogs given uncoated enzymes had a better response to therapy as reported by Hall et al. (1991), but more recent work has not shown such a difference (Simpson, 2005). Due to the associated deficiencies in cobalamin with this condition, supplementation with vitamin B12 is required as part of ongoing management (Simpson et al., 1989) to ensure the dogs are receiving a complete balance of nutrients.
How to determine if a dog has pancreatic exocrine function?
In dogs, pancreatic exocrine function is reliably assessed by measuring blood trypsinogen levels using the serum trypsin-like immunoreactivity (TLI) test. A value below 2.5μg/L is highly suggestive of EPI (Suchodolski and Steiner, 2003); however, diagnosis is more difficult when EPI is subclinical (Mansfield, 2015). Any dog presenting with gastrointestinal signs should be considered worthwhile of investigation for EPI because of the varied presentation of these cases, which do not always follow the prescribed list of clinical signs (Batchelor et al., 2007a).
What is an EPI in dogs?
Canine exocrine pancreatic insufficiency (EPI) is a digestive disorder resulting from the insufficient secretion of enzymes from the pancreas. This condition is frequently attributed to pancreatic acinar atrophy (PAA) in the dog, in which the enzyme-producing acinar cells are believed to be destroyed by a hereditary autoimmune process ...
How old is a dog when it has EPI?
EPI can occur in dogs of any age, but signs are usually first seen between six months and six years of age (Hall et al., 2003). The exocrine pancreas has a large functional reserve resulting in clinical signs being frequently observed quite late into the disease process where circa 90 percent of the functional mass of the acinar cells have been ...
What is the best diet for dogs with EPI?
Historically, dogs with EPI were fed a diet that was digestible with relatively low fibre and low-to-moderate fat levels (Hand et al., 2011), because fat is considered the most difficult nutrient for the intestine to assimilate and lipase activity is the limiting step in digestion of fat (Simpson, 2006). The rationale for lowering the fat content is that intestinal bacteria metabolise unabsorbed fat to hydrolysed fatty acids, which stimulate secretion of fluids in the distal small intestine and colon, potentially worsening the diarrhoea (Westermarck et al., 1995; Simpson, 2006). However, a canine EPI study found that feeding a moderate fat, low fibre, highly digestible food decreased flatulence, borborygmi, faecal volume and defecation frequency compared to feeding the original diets (Westermarck et al., 1995). In another study, a diet with up to 43 percent calories from fat, with a focus on the digestibility of the protein, fat and carbohydrates, yielded positive results in reduction of clinical signs (Suziki et al., 1999) compared to diets containing 18 and 27 percent of calories from fat. In a study of dogs with experimental EPI, a high-fat, high-protein diet in combination with enzyme replacement therapy optimised fat absorption (Suziki et al., 1999).
What is the pancreas of a dog?
The pancreas of the dog is a V-shaped gland located in the cranial abdomen comprising the exocrine (acinar cells) and endocrine (islets of Langerhans) portions. The exocrine pancreas secretes digestive enzymes, fluid and bicarbonate in response to food ingestion (Singh et al., 2018).
What is the best diet for dogs with pancreatic insufficiency?
In addition to supplementation with replacement pancreatic enzymes and vitamin B12, feeding a highly digestible, high energy density, complete and balanced diet is recommended. High-fibre diets should be avoided, as fibre may interfere with the fat absorption including essential fatty acids and vitamins.
When should you contact a veterinarian?
If you feel that your dog or cat is eating voraciously but not gaining weight or losing weight, if your pet has any vomiting, diarrhea, change in stool color, or change in appetite, please see your vet as soon as possible. Pets with untreated EPI will become extremely sick and can starve and die, even while being fed.
What does a TLI test show?
A blood serum TLI test (trypsin-like immunoreactivity) showing a concentration of ≤2.5 mcg/L in dogs or ≤8.0 mcg/L in cats means they have Exocrine Pancreatic Insufficiency. There is also a test for the presence of a pancreatic enzyme called elastase in the stool. However, this can be unreliable to diagnose EPI in dogs with chronic or co-existing gastrointestinal disease.
How to treat a dog with a swollen pancreas?
Treatment is chronic/lifelong. Your vet will prescribe your pet a pancreatic digestive enzyme powder (or tablet/capsule) to mix into your pet’s meals daily. Your vet should prescribe the amount of enzyme and monitor progress until the lowest amount needed to maintain a healthy pet has been ascertained. This may take weeks to months, depending on each animal and their condition when first presented to the vet. You may also discuss feeding raw pancreas as an alternative to enzyme powders with your vet. Sadly, many animals may have this condition and it goes undiagnosed or misdiagnosed for some time before treating it properly.
What is the pancreatic insufficiency in dogs?
The pancreas is an organ that has many functions, including producing enzymes to help digest food from what is called the ‘exocrine’ portion of the pancreas (there is also an ‘endocrine’ portion). EPI is a syndrome where the pancreas does not produce or secrete enough of these enzymes.
What causes EPI in German Shepherds?
1. The most common cause of EPI in German Shepherds, Rough Collies, and Eurasian breeds is atrophy of the acinar cells of the pancreas
Why is B12 not absorbed?
Deficiencies in cobalamin (vitamin B12) occur due to decreased absorption without the help of ‘intrinsic factor’ , an exocrine pancreatic enzyme whose production is decreased due to damaged cells. Vitamin B12 can be supplemented with injections and/or oral supplements.
What is the effect of EPI on the pancreas?
This decreases the body’s ability to digest food, and in turn, reduces the amount of nutrition able to be absorbed.
What is Exocrine Pancreatic Insufficiency?
Exocrine Pancreatic Insufficiency, or EPI, also referred to as Pancreatic Hypoplasia or Pancreatic Acinar Atrophy (PAA), is a disease of maldigestion and malabsorption, which when left untreated eventually leads to starvation . One of the major difficulties with this disease is in the prompt and accurate diagnosis. Astonishingly, visible symptoms may not appear until 80 to 95 percent of the pancreas has atrophied.
Why do dogs have patty stools?
Dorsie Kovacs, DVM, of Monson Small Animal Clinic in Monson, Massachusetts, has seen some young dogs with false-positive EPI readings. Even when they display the lighter-colored “cow patty” stools, something other than EPI may be the cause. Sometimes a food allergy or an overabundance of bad bacteria has irritated or inflamed the pancreas, temporarily inhibiting enzyme production. In these situations, says Dr. Kovacs, it’s important to put the dog on a pancreatic enzyme supplement for two months, allowing the stressed pancreas to heal. The dog should then be retested to either confirm or rule out EPI.
How long does EPI last?
Severity of the disease may vary, making it even more difficult to diagnose. EPI can be subclinical (no recognizable symptoms) for many months, sometimes even years, before it worsens and becomes noticeable. The symptoms can be exacerbated by physical or emotional stress, change of food or routine, and/or environmental factors. The most common symptoms include:
How much fiber is needed for EPI?
Sometimes all that’s needed are supplemental enzymes and the standard recommended dietary modifications: no more that 4 percent fiber and no more than 12 percent fat (on a dry matter basis).
What is the best way to treat EPI in dogs?
Enzyme supplementation is the first step in managing EPI. The dog will need pancreatic enzymes incubated on every piece of food ingested for the remainder of his or her life. The best results are usually obtained with freeze-dried, powdered porcine enzymes rather than plant enzymes or enzyme pills.
What caused Pandy to have a large stomach?
Pandy’s voracious appetite, large voluminous stools, and aggressive disposition were all caused by a medical condition called exocrine pancreatic insufficiency (EPI).
How many units of lipase are in a teaspoon of enzyme powder?
Prescription enzyme powders range from 56,800 to 71,400 units of lipase; 280,000 to 434,000 units of protease; and 280,000 to 495,000 units of amylase per teaspoon. Pancreatic enzymes are also available as generic pancreatin. Strengths of 6×10, 8×10, etc., indicate that the dosage is concentrated.
What is exocrine pancreatic insufficiency?
Exocrine pancreatic insufficiency (EPI) is the inability to produce sufficient pancreatic enzymes to digest fats, carbohydrates, and proteins. This difficulty in digestion leads to poor absorption of nutrients which commonly causes weight loss despite a normal or increased appetite.
What is the pancreas?
The pancreas is a v-shaped gland lying close to the stomach and small intestine. Secretions from the pancreas are carried to the small intestine by the pancreatic duct.
How is the condition diagnosed?
Simple blood and fecal tests can accurately detect if the condition is present. Canine trypsinogen-like immunoassay (cTLI) is the preferred diagnostic test for EPI. cTLI in combination with Vitamin B12 and folate level tests gives the best assessment of your pet's pancreatic function.
Is it possible to treat EPI?
Cobalamin (vitamin B12) supplementation may be considered by your veterinarian when hypocobalaminemia is documented. Treatment is usually for the rest of the dog's life. If elevated folate levels are detected indicating an overgrowth of bacteria in the small intestine, then an antibiotic called tylosin (brand name Tylan®) may be prescribed.
Is diabetes involved with the condition?
Rarely, in cases that are the result of chronic pancreatitis, the endocrine cells that produce insulin can also be affected. In these cases, diabetes mellitus (sugar diabetes) may also be present.
What is the prognosis?
Once an accurate diagnosis has been established, most pets do well with treatment.
What is the inability to produce sufficient enzymes to digest fats, carbohydrates, and proteins?
Exocrine pancreatic insufficiency (EPI) is the inability to produce sufficient pancreatic enzymes to digest fats, carbohydrates, and proteins. This difficulty in digestion leads to poor absorption of nutrients which commonly causes weight loss despite a normal or increased appetite.
What is an EPI dog?
EPI is a digestive disorder which impacts a dog’s ability to produce the pancreatic enzyme needed to digest his/her food. It may also be referred to as pancreatic acinar atrophy (PAA). Without supplemental pancreatic enzyme added with each meal, dogs with EPI are not able to digest their food and show symptoms of starvation, including weight loss, loose stools, and increased appetite. While currently there is no cure, EPI is readily treated by adding appropriate pancreatic enzyme supplements to each meal.
How to treat pancreatic enzymes in dogs?
Treatment consists of supplementation with pancreatic enzymes. Your vet may provide guidance on how much to use, based on the results of the cTLI test, however, there is often quite a bit of experimentation involved to get the amount just right, and to find the right food. The enzyme must be added with each meal (it does not stay in the body but is digested with the food). Without the enzyme, your dog is starving as s/he passes anything it eats through her/his system - basically undigested. Hence, the large cow-pie poops and the weight loss.
How long do EPI dogs live?
Anytime you hear your pet is sick, or needs treatment it is a scary confusing time. EPI dogs can continue to live a full life and do all the activities they did before, EPI, in and of itself, when treated , does not shorten a dog's lifespan, The key is successful management. Pictured to the left is Maia. Maia, now 7 1/2 years old, was diagnosed with EPI when she was about a year old. She is a joy and we can't imagine our family without her. She has mentored GSD fosters who have come in and out of our home - teaching them the ropes of life in a loving home. Her EPI care is routine for us. She gets love, toys and ice cubes in lieu of most treats, although she enjoys a dried tripe stick or probiotic treat, on occasion. She gets a combination of powdered enzyme and fresh frozen pancreas with each meal and thrives on this diet. At more than 90 lbs, we actually have to watch her weight, now that she is getting older. Maia's idea of a great day includes chasing squirrels, hiking in the park and going for a car ride.
What is the most common complication of SIBO?
SIBO: The most common complication is SIBO (small intestinal bacterial overgrowth). It occurs when undigested food sits in the small intestine and is attacked by bad bacteria, causing diarrhea and weight loss. SIBO usually responds to a course of antibiotics (typically, metronidazole (flagyl) or tylan).
What is the best way to treat EPI?
Porcine (pig) enzyme powder is the main method used to manage EPI. It is commercially available and easy to use. The enzyme supplements, typically, contain a combination of 3 digestive enzymes (lipase, protease and amylase). The enzyme is mixed with warm water to activate and the food is coated with the enzyme.
Do probiotics help with diarrhea?
Probiotics may help to maintain a healthy digestive and immune system by increasing the good bacteria in the digestive system. The addition of daily probiotics to an EPI dog’s diet may reduce the frequency of SIBO and diarrhea. Canine probiotics come in several forms: capsules, powders, liquids, pills, gels and soft chews. FortiFlora and Proviable DC are two such products. These products do not require a prescription.
Is it hard to prepare food for an EPI dog?
Preparing food for your EPI dog isn't hard – it does take some extra planning and effort but becomes the norm in short order, EPI dogs may continue to live a full life and do all the activities they did before, EPI, in and of itself, when treated , does not shorten a dog's lifespan, The key is successful management.

Pathophysiology
Health
- EPI may affect a dog's gastrointestinal system, as well as general nutrition, and can cause problems such as weight loss and chronic diarrhea. The condition is thought to be hereditary in German Shepherds.
Other animals
- The condition or disease described in this medical article can affect both dogs and cats. If you would like to learn more about how this disease affects cats, please visit this page in the PetMD health library.
Symptoms
- EPI may cause digestive problems, malnutrition, and/or improper absorption of nutrients into the body, which can contribute to an overgrowth of bacteria in the intestines. Symptoms may include chronic diarrhea; weight loss despite a normal or increased appetite; frequent or greater volume of stool and gas; and coprophagia, a condition which causes an animal to eat its own stool.
Causes
- The most common cause of EPI in dogs is idiopathic pancreatic acinar atrophy (PAA). The enzymes responsible for aiding the digestion of starches, fats, and proteins, are produced by cells in the pancreas known as pancreatic acinar cells. PAA develops when these cells fail to function properly, thereby leading to EPI. The second most common cause of EPI in dogs is chronic infla…
