Indestructible
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
Finally found a chew bone strong enough for our pit mix, would highly recommend for an agressive chewer! Will buy again

My four approve
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
My dogs, which I have 4, 2 labradors, one Jack Russell and one medium smallish mixed breed dog, all really love the bones. Three of them seem to be vigorous chewers the mixed breed girl being the toughest one on bones. These bones are holding up really well and the dogs really seem to like them. The dogs have not been able to get any big chunks off of the bones so I feel safe letting them have them even when I’m not watching. I would recommend these to Pet owners.

I have a medium sized dog and these were to big for him. A bigger dog would love them. Great for chewers.

Durable and fun for dogs
This is so easy to fill and my dog loves it! He got it when he was under a year and in his chewing stage and it is still intact. Very durable

FANTASTIC!!
Our dog Tigger has LOTS of energy. 😅 Even with my husband taking him to run alongside his bike around the block three times the other day, Tigger wasn’t even panting by the end. 🤣 I was talking to a new friend who mentioned more mental stimulation could help. Last Tuesday evening, he learned “give paw” within about 15 minutes. Hmm he’s a SMART pup. 🤔 Bonus…teaching him that seemed to really tire him out. From that point, I looked up dog mental stimulation toys here on Amazon and bought three puzzle feeders—this one is one of them. They’ve been amazing!! Tigger has been slowly catching onto how to get the food, which stops him from eating so dang fast AND also exercises his canine brain. ⭐️⭐️⭐️⭐️⭐️ I HIGHLY recommend something like this if you have dogs that have boundless energy or just seem like no amount of exercising helps calm them down.
