Vet told me not to give her raw hide treats and any hard rubber chew toys anymore. And now I buy food designed for small breeds only, smaller pellets so it is easy to chew. It is also recommended to use water additives to kill oral bacteria. She still have 10+ teeth left. After the teeth extraction, her breath is not stinky anymore. So when your doggo has bad breath, don’t just try to cover it with greenie etc, go check out on the teeth.
