Just discovered lumps in both rear legs of my Westie. She is 14. At first I thought it was her leg muscle, then realized it was not. Both legs have one and they are between a quarter and a fifty-cent piece size. I have a vet appt. for Monday, but wondered if anyone else has encountered this. "When it rains, it pours" seems the case. I am awaiting biopsy results on my 6 yr. old chihuahua, who has a tiny bump in one of his picky glands. Then I discovered this. It's been a bad week so far. Thanks for any info.
