OK our fur babies are very fussy so didn't hold out high hopes when introducing something new, but they took to these straight away. I prefer giving them the duck variety as I think healthier than pork, but they will even eat the fish. There is obviously something in them, when even fussy dogs will happily gulp down something new. They are a nice sized strip for small to medium dogs as a treat, but think they might get a bit lost on a large dog.
