The best safe, chew toy that offers variety and a challenge to keep your dog occupied.
Size: Medium, Style: Bristle Bone
My 60-lb, male Golden Retriever LOVES this bone. My first mistake was I put it together too tight; second mistake I loosened it too much and he had it pulled apart in no time. Now, it's just right. He wasn't sure about it, honestly, for about 5 hours. He is a chewer, he gets bored quickly, he's such a great dog I wanted him to have something indestructible, safe, and allow him different types of chewing in one toy. OH MY GOODNESS! This toy checks all the boxes. I did think I bought a Large; turned out to be a medium which is really perfect, for 50 to 90 lb dogs. And what came with this purchases was a bag of the treat rings. So glad I did! Finding the right chew toy to occupy this adorable boy has been a challenge. PetSafe, you met the challenge! Thank you so much!!

Great to stop Doggie boredom/barking
Size: Extra Small, Style: Bristle Bone
For tiny dogs, these are great ways to entertain the pups and get them to clean their own teeth; I have had one for 5 years and the dogs never were able to harm the white parts. I gave it to a pup that was homeless and I didn't have the heart to take it back later - It is quiet as a mouse and fits perfectly in tiny dog mouths. You do have to have their raw hide inserts but they're easy to find, not expensive, and again is great for boredom time for the dogs.

Favorite chew toy
Size: Medium, Style: Bristle Bone
Pros: this is our dog’s favorite toy. She loves to eat but isn’t much for chewing. At 2 years old, her teeth were already looking pretty bad because she swallows everything whole. That makes most chew toys dangerous. This is the first toy that she chews aggressively. At first we had to give it to her in short spurts because her gums bled. That’s stopped, her teeth and gums look healthier, and she carries it around with or without the inserts. She loves it.
The con: the bristles come apart after aggressive chewing. She swallowed some and I caught the other side coming off.
So whenever I see this on sale, I buy several new ones. I don’t try to make it last and I check it often for damage.

Dog treat and chew bine
Size: Medium, Style: Bouncy Bone
This was an ok purchase for my little dog. After eating the treats. She definitely liked this treat. She is 2 years old and loves her treats. Disappointed, in that it does not last as long as they said it would.
