Fun Dog Fetch Balls
Color: 3 Colors
Ordered these for my dog for Christmas and he loves them. He has a blast running up and down the hallway with them. Easy to play with, cute and fun. Not very noisy, I actually didn't know they squeaked until I stepped on one. Very quality and sturdy. Good value for the money. Package arrived timely and as described. Would definitely order again.

Tough ball. Perfect for large chewing breeds.
Color: 3 Colors
My German Shepherd Dog is a year and half old, and she loves these. They truly are pretty indestructible. It took her a little bit to figure out how to squeak it bc they are tough, but now it’s easy for her. They bounce well too. They are larger than a normal tennis ball but a good size for a large dog. Luna is 85 lbs. I would purchase they again, but I probably won’t need to for awhile.

Enjoyable For Our Dogs
Color: 3 Colors
Very durable material. They have a little squish too them for easy pick up for our 50 pound dogs. Our dogs love all balls. They have a little weight to them, but not excessive for a medium to large size dog. We have an English Springer Spaniel and a Goldendoodle. Fun for playtime, but you probably won’t want to throw them around the house.

A little too hard for our dog.
Color: 4 Colors
These are definitely durable balls. They are a harder than our dog prefers. He does play with them a little and enjoys squeaking them, but he doesn't like to play fetch with them and that is primarily the only thing he really enjoys doing with balls.
