How old is your dog? I was commented on how white's my girl's teeth are, she will be two in June. I also said maybe because shes young, but again theres another member in the other forums whose dog is 11 months old and her teeth are completly horrible. I dont know why my girl has such white teeth, they shine too. I give her your regular kibble mixed with wet food. I give her kibble from Wal Mart yeah it might not be the best BUT now she has no more food allergies, her coat is completly shiny and so are her teeth see some dogs dont need expensive or special diets
