My dog has the same thing...It doesn't bother her either, but I took her in anyway. I had it tested and it is what they call mesenchymal proliferation they said it is some sort of cancer. It is locally aggressive, but is slow to spread throughout the body. If I have it removed it is sure to grow back. However, no one can tell me how fast. They just tell me that it will eventually make her lame and I will have to put her down...sorry for the bad news
My Dog Has A Lump By Her Right Front Leg It Wasnt There Yesterday. We Just Got All The Ticks Off Of Her And Then The Lump Appeared, What Would The Cause Be?
Allegeries. a cyst maby. cancer. hard to say. size in this case matters.
So does mine. It looks like a tumor but it doesn't seem to bother her. My sister who had a dog for 18 years said it was nothing to worry about but I think I'm going to take her to the vet anyway.
