Why does my dog have a small bump on its chin?
Expert Answer
A small bump on a dog’s chin may be a skin problem from eczema, fungal infection, or parasite infection. Dogs easily wet their chins while eating or drinking, and long-term dampness can trigger eczema. Also, if the dog has external parasites, their bites can cause bumps. In addition, skin bumps may come from fungal or bacterial infection. You can try disinfecting and soothing the bump; if it doesn’t improve, take the dog to a veterinary clinic for examination and targeted treatment.
My dog's chin bump was just eczema from a slobbery water bowl, kept it dry and it cleared. But bumps can also be fungal, mite, or bacterial, so if disinfecting doesn't help in a few days, a vet should look. Wipe the chin after drinking and use a clean bowl, damp chins breed trouble. If it's growing, oozing, or he's bothered by it, don't keep guessing with home care, get a proper diagnosis.
