Not for aggressive chewers
My 14 pound puppy chewed a big chunk out within 30 minutes. Would not recommend if you have a dog that likes to tear into things

Not for aggressive chewers as labeled; poor quality
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!

Terrific toy for puppies!
I love this dog toy! I put treats inside the soft teeth of the toy so that my puppies have to work to get them out. By doing so, they are cleaning their teeth and enjoying a mental challenge at the same time. I love watching them roll the toy across the floor as they try to figure out how to get the treats out. Adorable! And it keeps them occupied for a long time.
