I have a big 1 year old German shepherd Collie Lab cross who is recovering from a hip replacement. This buffalo stick was brilliant, it lasted for ages and our pup is an aggressive chewer who usually has any treat gone in a few minutes. It provided hours of mental stimulation and tired him out. It’s not smelly or sticky - I have removed it a couple of times as my boy almost falls asleep from chewing for so long! Can’t wait for more to come into stock!
