I brush her teeth everyday. She doesnt eat anything, but her kibble, and the occasional milk bone. She has very, very little tarter. Shes had this problem before, and it went away within a couple day, but just came back. L she does chew on her toys a lot, and I leave them with her when I'm gone. I was thinking maybe she chews so much that her gums get raw? Shes also outside a lot, so maybe she got a hold of something tough and cut her gums up? Shes a 3 year old apbt. Thanks. Also the redness is mostly around her molars.
