IMHA is a condition of the blood that causes severe anaemia. IMHA causes the body (more specifically the immune system) to attack and destroy its own red blood cells. It’s most common in middle-age dogs (4-7 years old) and pedigrees.
IMHA can develop either very slowly or very quickly. If it develops slowly, your dog may just appear a bit quiet or low on energy. If it happens quickly your dog may develop pale gums, rapid breathing and might even collapse.
Although IMHA is a serious condition, treatment is usually successful if it’s given quickly.
