In a study once made of neoplasm's in dogs, about 8 per-cent were in the testicles. This occurs in a high percentage of old dogs.When a growth occurs in one testicle, the other generally atrophies.When the testicle with the growth is removed, the shrunken testicle usually increases to normal size again, and there may be a return to normal production of sperm.
Some tumors growing in the testicles may cause the dog to take on female characteristics. He develops enlarged nipples, does not lift his hind leg when urinating, and has no interest in mating with bitches.
