Small growth on the top of my dog’s paw

Three days ago I noticed a growth on the top of my dog’s paw at the base of the web between her first and second toenail. It is attached at a small place on the growth.

The only example I can think of is if you blew a balloon up and held the part of the balloon where your mouth went to keep the air inside, the balloon would seem “attached,” but you could push it from side to side and move it around. The growth on her paw is “mobile,” I guess you would say … it is not like a cyst. It is attached at a small point on the growth, but the rest of the growth can be moved from side to side.

I have seen her licking it, but rarely… maybe three times in the last three days. So I don’t get the impression that it bothers her very much at all. When I touch it and move it around, she nudges her nose at me to stop, but it doesn’t seem to cause her any pain.

It looks pink with a whitish roughness on the surface. When I noticed it, it was this very size, and over the course of the last three days it has not changed in size or color. I have read that it could be just a wart, but I have also read about papillomas, malignant tumors, etc.

A little more background about her…

I adopted her as a rescue about two and a half months ago. She is a West Highland White Terrior. As far as I know, she doesn’t have any acute health problems. The only thing I can point out is that her teeth are very brown, which I attributed to her diet being poor most of her life. She was caged all of her life and just used to breed. The rescue folks think she is about five or six.
