Q. The right side of my chihuahua 's mouth has a knot and is swollen. It appeared last night and now it looks really saggy underneath her neck. Why?

Answered By

A. It's really hard to say, since I'm having a hard time picturing exactly what the problem looks like. At 11 months of age and in this area, it could be a problem with a tooth that's trying to grow in, a salivary gland problem, or an enlarged lymph node. If you'd like to do a consult you can send me some pictures and I can try to help more, otherwise I'd recommend getting this checked out by your vet.
