Our dog loves it but it wasn’t durable enough to last
Color: Dogwood Jack, Size: Large, Color: Dogwood Jack, Size: Large
Our lab took to it as soon as we gave it to her. Perfect size for our 80 lb yellow lab.
However, now that it’s in about 10 days, she’s able to break off chunks from this bone that are dime size or larger, and we have to throw it away

No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long.
I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Great for big chewers
My dogs have to have these. Have to. When I come home from work they each grab one and prance around like they just caught a moose or something. This past weekend my big boy doodle wanted me to toss it to him like I do his tennis ball. He kept dropping it for me to toss. It was hard explaining that it would be the worst boop he ever felt.
Ok, lets talk about longevity. I've had these for over a month and they still look great. Barely looked chewed at all. These are tough and poodles supposedly have soft mouths but mine chew on these a lot. They are large. My female is 60 pounds and my Dood is 90. These chew toys keep my pets engaged when I am busy doing all the things at home so that takes some pressure off of me. I would buy them again for sure.
