Today I noticed my dog licking her paw endlessly, and when I examined it, I found a hard, red lump about the size of a large pea, located at the base of her dew claw. She doesn't act like it hurts, because she let me touch it. She doesn't limp at all, and is acting like her normal self in every way. If it wasn't for her licking the lump, I would not have even suspected anything was wrong with her.
I viewed the lesion. It could be a histeocytoma, which is a benign dermal mass that occurs in young dogs, or it could be a sarcoma, or abscess. It really would be best to take your dog to your vet for a biopsy which will give you a definitive diagnosis.
