My dog, border terrier-mix, male, is 9 years old. About 2 years ago, I noticed a black spot the color of the rim of his bottom eye, it is now about 1/4 " long. It doens't seem to bother him and is still black. I can't afford to take him to the vet and am really concerned. Now I notice he is getting very large discolorations on his belly, where his legs connect, what we call armpits, his legpits? lol Don't know what else to call them. Also his bottom lip has a white discoloration on it. Does he have Cancer? And one more thing he has a red lesion on his foot, which has now turned black. He doesn't seem to be in any pain at all. Still runs around and plays. I don't know what to do, I just have no money for a Vet. Maybe someone can help. But, let me assure you if I thought he was in any pain whatsoever, I would 'beg, borrow, steal!" well ok not steal, but make sure he was not suffering. I really love my dog so much, he belonged to my mother, who passed away. Thanks again for any help.
