I have no doubt theres a genetic component , and im sure a badly bred doxie would have mouth issues too.. all i could think of this whole thread is god how bads that dogs mouth going to be.. Critters mouth has had a massive overhaul like that before and needs it again already and its been less than a year. I know it sounds bad but im not putting myself through this "bad teeth" bussiness again with a senior dog. If the problem develops fine i'll deal with it, but i'm not knowingly doing it again from the get go. And its not even the money factor! Everytime they knock my dog out I think shes not going to wake up, the BYB senior dogs are just a mess. and Yes, i don't think anyone is trying to be mean, we are all just very concerned. I have 5 dogs and its a MASSIVE comitment, i eat, think, breath, sleep these dogs and my bank account shows it.
