Great strong chew toy. It's very strong and does not tear apart like everything else. At the same time it is not hard plastic like the last brown one I ordered that could break my dog's teeth. My dog is a 2 yr old 14 lb Chi mix with a super strong bite. He tore all the stuffies up and even the nylon toy that was supposed to withstand a lot. This is the one toy that could outsmart him. I play fetch with him and it has a nice weird hop due it's shape so it keeps him interested and surprised. It's a bit heavier than other similar toys and I'm guessing bigger dogs would definitely like it too. I'm very pleased after buying so many others that were easily chewed up or too hard.

Unsafe and absolutely garbage

Color: Yellow Frisbee, Size: Large

If I could give this zero stars, I would. My dog had it for approximately two minutes of playtime, I didn’t even get to throw it, and it already had holes in it. He wasn’t chewing it or playing aggressively. He simply had it folded in half in his mouth and it tore. This toy is not safe for dogs.

Perfect ball for my Chihuahua

Color: Multi Meteor Ball, Size: Small

My dog is a Chihuahua. The small size is perfect for her. She loves chewing on the ball and loves the crackling noise from the material inside. I love that it is strong enough, she cannot tear it apart or is she able to remove the material inside. Perfect for her.
