He always had a black mole like growth on the outside of the breast ... All of them go out it's a wart or a skin tag. For 6 years he has been asked, then 2 days ago it started swelling and filling with fluid. It is now the same color is brown, but how it continues to grow, I see the stretching of the skin as you probably a lighter color. Well, it's like a big acorn has in all directions, not just the acorn,:), or a big brown grapes. He is now owned and licks all the time. It seems serious, it might be painful, and frankly, I'm afraid that I might try to chew off. How can one seriously gland and nipple, the mole, what? He is a boxer mix Rott and I noticed a few other places that are small but meaty black and a little of it before. Any advice would be great. Vet said $ 400 to remove it, but I'm a shy zeros there is a home remedy? Thanx a lot!
