She goes through things pretty quick, and I know she could have destroyed ...
Size: Large (Pack of 1), Style: Stick Large
My dog is a heavy chewer, and player (Doberman). I got one of these when she was a puppy and about 2 years later it broke in half from periodic chewing and tugging. It was one of her favorites and I was impressed it lasted so long so I ordered another one. She goes through things pretty quick, and I know she could have destroyed this fast as well, but it probably helped that she had other things she was supposed to chew on instead. We never encouraged her to chew this, but she loves bringing it over so we can throw it, or tug on it. Never had any issues with the squeaker (until the first one broke in half after 2 years). I would recommend it, but try to encourage it for play and not for chewing. It is flexible and durable and handles a 70lb Doberman dangling from it periodically.

Fun!
Size: Large (Pack of 1), Style: Stick Large
This was nice and fun for my dogs. Squeegee could have last a little longer. It lasted about 2 weeks until they were bored of it but I think that’s more of a my dog issue.

High quality, durable, loved by my chewer *
Size: Medium (Pack of 1), Style: Stick Medium
Excellent chew bone Toy for aggressive chewer. I've purchased this same brand bone/ Toy for several years. One lasts at least 1-2 years ( if it doesn't get run over by a lawn mower). Lol. I usually pay $8-$9 for one in retail stores. This is an excellent price at $6.
Squeaker stops after a few months but my Field Spaniel dog is deaf now anyway! He loves chewing on this for his gums and when people are gathered in the same room he just starts chewing and enjoying himself in the midst of fellowship.

Not for aggressive chewers
Size: Large (Pack of 1), Style: Stick Large, Size: Large (Pack of 1), Style: Stick Large
I got this for my 95lb lab who is an aggressive chewer thinking that it looked durable and would last a while. He tore it apart within an hour and I had to throw it away.

Felt durable but it couldn’t hold up
Size: Large (Pack of 1), Style: Stick Large, Size: Large (Pack of 1), Style: Stick Large
I really thought my pet wouldn’t be able to destroy it but it’s in tiny pieces in the trash now. we played together and she was gentle I guess because she didn’t bite or tug hard at all I left her alone with it like I’ve done before but this time she broke it down in chunks. Did not have this toy for more then 24 hours.
