It can be a worrying time for you and we keep you frequently updated and informed as to the progress your pet is making.
What is the treatment for IMHA in dogs?
Treatment may involve hospitalisation for a number of days, blood transfusion and other supportive care along with suppression of the immune system. Gradual withdrawal of therapy whilst monitoring the disease is an important part of successful therapy. In the initial stages, the outlook for dogs with IMHA is guarded.

Some types of acquired hemolytic anemia are short-term (temporary) and go away over several months. Other types can become lifelong (chronic). They may go away and come back again over time.
How long can a dogs live with autoimmune hemolytic anemia?
What is the outlook? The prognosis with IMHA is variable, carrying a mortality rate of 30% to 70% within 1-2 months of diagnosis. If patients suffer IPT at the same time, or if the bone marrow is affected, the outlook may be worse. The condition can come back, and some animals need lifelong medication.
How successful are blood transfusions in dogs?
Blood transfusion in dogs is effective in restoring blood cells lost to anemia and alleviating the symptoms caused by that blood loss. The effects of transfusion are not permanent and last only as long as red blood cells remain in the system.
How long does it take for hemoglobin to increase after blood transfusion?
Abstract. Background: Equilibration of hemoglobin concentration after transfusion has been estimated to take about 24 hours, but some studies have shown that earlier measurements reflect steady-state values in persons who have not bled recently.

How long can a dog stay on Mycophenolate?
MMF is not myelosuppressive, and was actually developed as an alternative to azathioprine in human transplant patients. The recommended dose range in the dog is 7- 20 mg/kg PO or IV BID for 3-4 weeks, then 10 mg/kg SID.
What is IMHA treatment for dogs?
IMHA Treatment for Dogs. IMHA is a serious and life threatening condition that affects both dogs and cats. IMHA stands for Immune Mediated Hemolytic Anemia. In essence, this means that your pet’s immune system, which typically fights of invaders and infections, is now fighting your pet’s own red blood cells. This results in the red blood cells ...
How to tell if a dog has IMHA?
Signs of IMHA may include collapse, weakness, increased breathing rate, yellow or pale gums. Some dogs will present with red or black urine. Many dogs have a fever, and most feel unwell, with a poor appetite or even vomiting.
How many blood transfusions do dogs need?
Most dogs with IMHA require at least 1 blood transfusion, and many require two or more. Each blood transfusion has to be appropriate for your dog’s particular blood type and carefully administered over 4 hours to prevent transfusion reactions. While there are risks associated with blood transfusions, they are only used when absolutely required and can be life-saving. We obtain blood from healthy donor dogs; it is typically concentrated into “Packed Red Cells” to ensure that your dog gets the blood it needs as quickly and safely as possible. At VRH we have blood stored on-site ready to be given to your dog as soon as required.
How many dogs can survive IMHA?
With careful treatment, up to 75% of dogs with IMHA can make a full recovery and go on to lead a normal life.
What to do if my dog is anemic?
If your dog is anemic, your vet will usually recommend follow up blood tests to determine why your dog is anemic. There are several classic signs that can be seen on a blood test that can confirm IMHA although occasionally additional tests need to be performed to ensure that the diagnosis is correct.
What is the treatment for IMHA?
Other treatments that have been tried for IMHA include IV infusions of human antibodies (Known as IVIgG) which help block the immune-system attack. This is unfortunately very expensive and can be hard to obtain as it is preferentially used for humans. Its efficacy is variable between dogs.
How long does it take for a dog to recover from a steroid shot?
Steroids do have side effects when used for long periods of time at high doses, so this medication is typically tapered over 3-6 months as your dog recovers. Other drugs are often used to help treat IMHA or to reduce their dependence on steroids.

Can a thoracic radiograph be used for IMHA?
There have been anecdotal associations of several types of cancer with IMHA, so imaging of IMHA patients with abdominal ultrasound and thoracic radiographs is often performed. An abdominal radiograph to rule out zinc foreign bodies such as coins that could lead to hemolysis is also an important diagnostic step.
Is IMHA a differential diagnosis?
IMHA should be considered as a differential diagnosis in any dog with an acute onset of anemia that has evidence of hemolysis. An immune-mediated pathogenesis is supported by the presence of significant spherocytosis, a positive saline agglutination test, or a positive Coomb’s test. Any of these factors combined with evidence of hemolysis, ...

This results in a rapid onset of potentially life-threatening hemolytic anemia. Although IMHA can occur in any dog, one large study noted that purebred dogs represented 89% of all cases, with Cocker and Springer Spaniels being overrepresented. 1 Clinical signs of IMHA are often non-specific, including lethargy, inappetence, and weakness.
Does IMHA cause regeneration in dogs?
Although most dogs with IMHA have a strongly regenerative anemia, approximately 30% will not have evidence of regeneration at the time of diagnosis. 2 In the majority of these dogs, this is due to the anemia being “pre-regenerative,” meaning the bone marrow has not had adequate time to mount a regenerative response.

These include Dong quai (Angelical sinensis) and Rhodiola (Rhodiola rosea).
Can food allergies cause IMHA?
While food allergies may not have caused the IMHA, allergens in the food may cause further unnecessary stimulation to an already overstimulated immune system. Hypoallergenic diets will allow for adequate nutrient absorption without fanning the flames of an already inflamed immune system.
Can Imha go undiagnosed?
Dogs with IMHA can often go undiagnosed for several days , because the early signs are subtle and non-specific. The dog will act lethargic – he’ll just lie around, have no energy and not engage in normal play. As the disease worsens, the lethargy will become more pronounced.
