It is not as good as the official replacement: a little soft, takes a little more time to clean the teeth. But can be used. It is cheaper if you would not mind to clean teeth a little longer.

Had high hope on these. Think that it's such an awesome idea. However when you put it in use, it's kind of flimsy. Unless you have pure soil you can dig, if there are any rocks, roots, wood chip... Good luck to your fingers.

My dog who will eat anything would gag every time I came near her with these. Even covering the pill in peanut butter did nothing. Her previous multivitamins she would take without anything just chew the pill and be done. She does like the treat ones from this company but I was bummed about these considering it's way more for the same price the treat ones are.
