They last for months
Color: 3PC-Bacon-Brown, Pattern Name: Tough Dog Toys
This is my second order of this product. I have 2 medium size dogs and they love them. The nice thing is a 3 pack of these is that they will last them for a few months.

Indestructible

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.
