CET chews medium
I usually get the large ones from my Golden and though the medium would be better because he is old and is hard to chew, however, I'm going back to the large ones because he eat these ones right away and it defeat the purpose. I love this product anyway; I used it with me previous Golden and now with the one I adopted. It's great!
What is there to say?
My dog gets one of these things each night at bedtime. He loves them, they don't seem to make him sick, his vet says he has great teeth. But then, the vet said that before I ever started giving my dog these chews. Also, the vet still says he needs a teeth cleaning. Even though he's only 36 pounds (my dog, not the vet) , I give him the X-Large size for dogs 51+ pounds. They're expensive, but Revival sells them for less than I'm able to find them elsewhere. Oh, and his breath still stinks (my dog, not the vet). :-)
