Good buy
Color: Blue-Green-Orange
Babies didn't use them. Too tough for their mouths. They are to small. Good for a bigger puppy.

Mastiff mix puppy loves them
Color: Blue-Green-Orange
I have experience with large working dog breeds, and I've got a mastiff lab mix puppy, who at 5 months weighs 50 pounds and is teething hard, and chews on everything. Most chew toys I've tried broke within a few minutes, but these have held up. I like that the ones I received are hollow, so I can put puppy kibbles inside them to keep the dog busy in her crate, and slow her eating so she doesn't scarf down her meals and get sick. The hole is small, but I feed small sized "taste of the Wild" brand kibbles, and they would pour out of Kong toys within seconds. I have recommended them to other puppy owners.
My dog isn't an aggressive chewer, but for a teething puppy, these toys do seem to be ideal.

Nice material but do not recommended for aggressive chewers
Color: Blue-Green-Orange, Color: Blue-Green-Orange
Why did you pick this product vs others?:
The material is nice and easy to wash but definitely do not recommend for large breeds/ aggressive chewers. My big pup ripped one up within seconds of getting it. The ball has lasted!
