I have an unusual problem with one of my girls and hope someone can give me some tips. Lexi is two and has horrible breath!! I brush her teeth, and she only eats SO diet from the vet. She does not get treats except for the SO wet food that I cook and refrigerate. Of course she is my one that loves to give kisses but it is really bad. I dont want to get in the habit of giving her treats as they could cause crystals in her bladder. Does anyone recommend a good toothpaste, or natural remedy? Thanks!
