My rescue spaniel has o nly about 6 teeth left, she had very bad gum disease and teeth were almost completely encased in tartar. She has had this scaled off twice by the vet. I use a plaque removing paste but probably not as much as I should and she has what dental sticks she can cope with. Now she needs to go again. Is this a common problem with spaniels, Ive never had this with another breed ? My old 15 year old has only once had his teeth scaled in his life and they werent actually that bad!
