The toys body is very durable, but the squeakers were broken within minutes without tearing it apart
Color: Green Bird
This is a squeaky dog toy that was supposedly very durable. I have to say that the squeakers are not durable and were immediately destroyed by my husky. The actual body of the toy is very durable and they were not able to rip it apart. They were able to destroy the squeakers without damaging the actual exterior of this toy. The toy itself is pretty soft except where it’s made of rope. Since it didn’t have any stuffing come out I will say that it was durable enough for chewing. This would be suitable for large larger dogs and even smaller dogs. I do feel this is a good value for the money because they were not able to rip it apart. I just wish the squeakers were more durable inside because there’s no way to replace those.

Our dogs new favorite toy
Color: Green Bird, Color: Green Bird
Our golden doodle loves this toy. He isn't a highly aggressive chewer necessarily, but he has been known to destroy toys by chewing on them and such. This one, so far, has lasted over a month or so. It has turned out to be his go to toy when he's wanting to play with one. The squeaker isn't that loud and it's not that easy to find. I like that legs are rope material and makes it good for tug of war, which Max loves to do. The material is pretty sturdy and it is a good weight. Sometimes when the toys are too heavy Max won't catch them in the air, this one he catches in the air just fine. It's very cute and I think it will hold up just fine to our Max's level of chewing. I felt the price was quite reasonable considering how much he likes it.
