They're a little on the small side. Wouldn't give it to a full grown medium sized dog. Mine is small / medium sized, any bigger and I'd worry about him eating this too fast and choking on it. Also had it finished within about a minute, so not very long lasting!
Black field lab loves these
These bones are seriously good! My Jack Russel and Chihuahua love them, it keeps their teeth clean and the peppermint smell lasts too! As soon as I open a pack, the bones are devoured! My friend's dog is picky and he loves them too. Will definitely keep reordering. FULL MARKS!!
