I was searching for a squeaky toy but also a chew toy that wouldn’t break my dog’s teeth. We’ve already had to have one tooth pulled because our Jurassic Corgi girl cracked it on either a bone or a yak chew. She loves to play with this bone and chew on it and it has held up well. It still looks like new after several months and she plays with it daily.

Famous Squeaky toy. Good for puppies.

My dog’s favorite. However, He takes them outside when going to relieve himself. Forgets to bring back.

FUN TOY!

Got this a couple days ago and so far very pleased. Would give it 5 stars, but only had it a couple days - we will see how it holds up o er time. All 4 of my dogs love it, so much so that I ordered more today. It's got an awesome squeaker, and is flexible without being flimsy. My guys haven't destroyed it yet, and that's always a good sign.
