I just took a look at my pups teeth and one of them looks like it's about to fall out, its very loose...one of the front ones. I'm not sure how this happened bc he always gets his teeth cleaned at his groomings. Can it be saved? Has this happened to anyone else? We're already dealing w/ either mange or allergies and this is just putting me over the top w/ stress. I can only imagine how he must feel. I feel so horrible....
