Tumors of the spleen are common in older, large breed dogs. If the tumor is benign (non-cancerous), removing the spleen cures the disease –
if we can catch it before it ruptures and the pet bleeds to death. The prognosis is much better and the surgery expense is much less if we catch these tumors when they are small, like in the 1st picture. Regular examinations to palpate the abdomen, testing to look for abnormal red blood cells caused by the tumor, and x-ray or ultrasound screening, can all help us to catch the problem early. Another thing you can do at home is to always keep an eye on the color of your pet’s gums. If they look pale, instead of a healthy pink color, the dog may be bleeding internally. Other symptoms would be an enlarged abdomen, weakness, collapse, or poor appetite.
