My 7 month old puppy has been a big fan of these for quite some time. They are in every order, and he takes them to his bed to enjoy them. They don't last long but he usually chews them for a few minutes.
My pup really liked them, the first time I gave him one he fell for them, and the second time he took it to his bed and was kept busy, it was like not having a dog for a few minutes.
I bought it with my zooplus points to try it and I really liked them because even though they are meant to be a snack my dog chews them for long enough to be kept busy a while without swallowing them.
Leya likes them and although they are quite expensive both generations of my dogs have loved them.
I hope to see some sort of saver pack introduced soon.
