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.

Great enrichment
Size: 2.8in for Small & Medium Dogs
These are great for our 3 dogs, they’re durable and strong. The pup ford training treats fit great into these and it takes our dogs a good bit to get all the treats out. Easy to clean and a great enrichment toy, will buy again!

My dog looks forward to this every day
Size: 2.8in for Small & Medium Dogs
My dog used to have separation anxiety every time I left the house. I tried to find things to distract her when I left, but nothing kept her attention long enough for me to get out of the house. I stuff treats in this ball and she keeps focused and gets all of the treats out. Perfect solution to keep her occupied as I leave for work. Very easy to put treats in and I’ve had it for about 6 months now, which is great because my dog chews toys to pieces within days! High quality ball. I love it so much (well, my dog loves it so much), I bought one to give my neighbor’s dog.
