Not durable or for semi-active chewers whatsoever. While you think they look substantial and are marked for active chewers, beware! A puppy went through one in 5-7 minutes.

My Pointer is high energy and loves to jump. She gets 1 of these daily to help her stay healthy. She gets so excited when she knows it's time for her collagen roll. Its her favorite treat.

My 4 dogs disliked the product. My adopted dogs are each of a different breed type, however, all of them did not take to the flavor of these bully rolls.

My dogs loved them. But my dogs had terrible diarrhea from them. They only got one every other day. It took a week for their stool to get back to normal. Plus, they are not long lasting as advertised. Gone in 10-15 minutes.

My bulldogs LOVE these. Every night they go to the cabinet where I store them and put their nose on the cabinet door. When I go towards the cabinet they start twisting all around. They grab one a piece and both go separate directions.

My dog is over 100 lbs. He really enjoys these and makes short work of them. I like that they are good for him, they do however make a really big mess.

My three German Shepherds absolutely love these treats! I give each of them one every day and they look forward to it. They remind me when it is time. They do a great job of keeping their teeth clean. I was worried one time when my Sam's store was out of them, so I stack them deep. I dread the day they stop carrying them.

Great amount for the price

My Bull Arab dog is a heavy chewer and he loves them

My dog loves these - and they're a good price and generally on sale
