One of the most entertaining things you could buy. The dogs go crazy over it and have so much fun. It's a bit loud on hard floors, but honestly worth it for the laughs. Seems pretty durable too. I have 2 labs; one started out uninterested and the other started off scared of it, but not too long after, they both started going crazy, tossing and carrying it around while it shook.

Great customer service

Bought this for our dog for Christmas! He loved it! It sadly stopped working shortly after. Recently emailed the product site themselves and they sent a new one that week! Great customer service and great toy!!

My dog LOVES these balls

Awesome balls! Soft, squishy, and dog can get their teeth into them but they don’t get damaged. My dog absolutely loves them!

Durable.

These are great for my 13 lb Schnauzer. Just the right size to keep him occupied! He loves chasing after them when we play catch. They’ve held up well to his sharp teeth.
