Thanks everyone for your thoughts and kind words! The vet told me that I'm doing everything right-hand tucker may just have bad teeth. He lost several teeth during the cleaning in addition to the one they pulled. He has almost no front teeth now. They did tell me to feed him a larger kibble instead of the small breed. She said he will have to chew the larger pieces and that may help. I still felt a little guilty, but y'all have reassured me
He is kinda cute now... Sticking out his tongue over and over...
Thanks again!
