Really disappointed in this item. My barely 16 lb., 1 1/2 yr old labradoodle chewed right thru the plastic in literally 6 seconds. I was going to toss it but at $18, the item should live up to its description-this toothbrush toy is rated 80% on the aggressive chew scale as per packaging…NOT AT ALL! She bit off a couple off chunks immediately, then proceeded to bite off the spikes…couldn’t believe how quickly the toy was destroyed & I took it away within moments of giving it to her.

great for my dog

my 1 y/o pomeranian won’t let me brush her teeth. she also needs a lot of enrichment. i love putting a dollop of toothpaste, some wet food & few pieces of kibble in this toy for her. it keeps her busy for about 10 minutes and she really enjoys playing with it while consuming everything she can out of it. wonderful way to enrich while giving dental care. she is also a pretty good chewer and it’s still in one piece!

Great Product!

Size: Medium, Color: green, orange, pink, Pattern Name: clean tuff bone bacon

My dogs love their dental chews! This product is durable and the perfect size for each of my dogs. I've purchased two of them (medium and large). One of my dogs is an aggressive chewer and this product is holding up. Hartz makes great pet products. I'm very happy with the product.

Winnie Loves Them!

Size: Medium (Pack of 3), Color: Orange, Green & Yellow, Pattern Name: Dog

My Winnie is an aggressive chewer and she loves these bones. They're indestructible and they must be delicious because she works on them every day. I was a bit concerned when they were out of stock for a few months. Please don't discontinue them!
