Durable and tough
Color: Red
Very durable and squeaker is still intact which doesn’t happen often with my mastiff mix. Definitely one of his favorite toys.

Chew toy
Color: Red
It’s a great chew toy for dogs and definitely keeps them entertained for hours however, it’s not durable enough for really strong chewers. I have two pitbull puppies and in five days he tore the end off of it. I do recommend for medium sized dogs.
