Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Perfect for Blind Dogs, Fun and Durable
Size: 2-pack, Style: Duo
My blind dog loves these Chuckit! sniff balls. She can easily sniff them out and plays fetch with them for 20 minutes a day, even running up and down the stairs. The balls are durable, bounce well, and the bacon and peanut butter scent keeps her engaged. I do wish Chuckit! would bring back the version with a tone so we could play fetch outside more easily. Overall, a fantastic toy for dogs that rely on scent and a fun way to keep them active.
