Why does my dog have bumps?

Your pet seems fine, and then all of a sudden, a new lumpy, bumpy mass pops up on his body, seemingly overnight. Sometimes these lumps and bumps can be caused by wounds, but other times they can be warts or other types of growths. Whatever the reason for them, they’re among the top ten reasons owners head to the veterinary hospital.

And that’s a good thing, since sometimes, a simple swelling can be a sign of a dangerous but treatable disease. The only way to be sure is by going to your vet and letting them assess the new development.
