Riley's 6 Inch Beef Collagen Sticks for Dogs, Collagen Chews for Dogs, Bully Stick & Rawhide Alternative, Long Lasting, No Raw Hide Chews, Single Ingredient Dog Treat - 5 ct

Sticks seem to be of good quality and very long in size. It's taking a while for our large dog to demolish them. They do leave some residue on the surfaces, as expected, but not terribly. Overall, very satisfied.

Dog loves them, these are thicker than some brands, so they last longer, yet they are less expensive than those brands as well. I’ll definitely buy again.

Our dogs love these! They help keep their teeth clean. No digestive upset. No smell or stains noticed on our brown carpet. They a few days with our medium sized dogs. We have these on subscription.

My dogs love it but unfortunately giving it 4 stars as the reason I got it for was to help keep my 8-month-old puppy occupied/busy and it didn’t last long. Based on others’ reviews I thought it’d last but it barely held up for forty minutes which is decent but less than her bully sticks or other options around the same price. So decent for most dogs but doesn’t last long for avid chewers!

Longest lasting ones I’ve found and they don’t smell disgusting!

So disappointed because my dog does not like these one bit. He sniffs them and walks away. I even put a tiny bit of peanut butter to entice him and he licked the peanut butter, chewed this stick for about 5 minutes and then walked away. That's what i get for buying a cheaper copycat of a much better and more costly bully stick. The thickness is good, it doesn't really smell too funky, the color does look a bit fake and it's a decent size. Not sure about teeth cleaning or diarrhea since my dog, and even 2 other dogs that I'm dog sitting, just plainly refused to chew on these so i say, spend a little more money and go for the better quality ones. The good ones clean my dog's teeth amazingly well and do not upset his tummy at all though.

I am not sure why but neither of my two dogs like these. I gave the bag to my neighbor and her dog won't eat them either I hope there are dogs out there that would enjoy them. I am disappointed.

Best collagen sticks! I’ve tried many different ones and these are the best as far as not splintering into little sharp pieces. I’m always afraid of a little sharp piece choking my dog and these get soft as she chews and doesn’t splinter. Highly recommended!
