Awesome squeaker toy!
Color: Green, Size: Large(50-90 lbs)
Noise level is expected. It’s a squeak toy. If you get annoyed by your dog having fun, get outta here. It’s a bigger toy so I don’t worry about choking. It’s bouncy and a tough material for our tough chewer. Color is whatever! Great toy.

It was fun while it lasted.
Color: Green, Size: Large(50-90 lbs)
This is a tough chew toy, but yep, it still got destroyed after a few uses. So my Siberian Husky strategically destroys the squeak in everything immediately. This one actually took some time. It's not super squeaky and is more challenging to make it squeak. I was pleasantly surprised that it the squeaker lasted a couple weeks. For the record my Pitbull got to it the 3rd week and it was completely destroyed in 2 further days. This is a very hard chew toy and I wouldn't recommend this unless your dog is also a destroyer of a the tougher toys. Even though it was still demolished they had a great time with it and it still lasted longer than most. I hope that helps and I hope you have a happy day.

Excellent heavy duty squeaker toy
Color: Green, Size: Large(50-90 lbs)
My German Shepherd LOVES this noisy toy. It is extremely well made, durable, LOUD, and heavy. I'm hoping this toy lasts much longer than the grunting pig that he absolutely loves, but tend to stop squeaking within a day or so. Definitely worth the money!

Terrifying jaw strength..
Color: Green, Size: Medium(30-55 lbs)
Have 2 Corgi and it scares me that they make this thing squeak. The bite pressure they have now from working out jaw to squeak this like it's nothing. Didn't expect our smaller corgi to be able to squeak this couldn't at first now she just goes ham on it like it's no big deal.

Great for a chewer
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog loves a hard toy and a durable one. My dog has been chewing on this for months and it is still holding strong. Because it is a hard toy when my dog brings this into another room with a hard floor and drops the toy it can be startling. My dog will choose this toy over others on a daily basis and brings the toy to other rooms.
