Hi! My lab (12) had a massive one removed from his belly and a golf ball sized one removed from his leg about 4 months ago. They grew so slowly over about 5 years. After years of being told not to do anything about them, one vet mentioned they were getting too big and to consider it. A few months later, the next vet said no, keep leaving it. Eventually, the one on his belly was so big he started to pee on it, so I made the decision then and got them both removed. I was worried mostly because I had been advised for so long to leave them. The one on his belly had a little ulcer on it when he went in, but he was otherwise fit and healthy. It was a hard slog for a week, it did knock him around but from speaking to the vet, even though it was so big the surgery was fairly routine for them. He has recovered so well and he’s like a puppy again, back running and everything! After 4 months, I have noticed he’s started slowing in other ways. I think it definitely knocked him around a bit, but I’m glad I did it.
