My puppy, who is a little less than five months old, has a swollen lump-like thing in her nipple. It looks like mammary tumor (I had an older dog that had this condition) except that it looks like there might be a bug bite on top of it. Can bug bites cause this kind of lumpy swelling?

I have never seen a bug bite cause inflammation of a mammary gland. Swelling is usually from mastitis - some type of infection and/or inflammation got into the teat. Please take her the vet for an exam. The vet needs to see her in person.
