A couple weeks ago we figured out that my Rednose Pitbull has a Histiocytoma, which is also refered to as a Button Cell tumor. It is pretty much a growth that grows on your dogs neck, head, or foot. In her case it was on the back of her neck. Well all they do is give you some drops and it goes away, pretty simple. Well i just noticed that i think another one is growing on the top of her head, Does anyone know how many she can grow, because i hate that she has them, she looks scary, lol!!! Thanx in advance!!
