Perfect size and very durable! Flexible but sturdy.
Perfect for my Frenchton puppy. Easy to pick up in her mouth and they are flexible but sturdy. Unfortunately lost all three already, lol, so guess I’ll be buying more. 🤦‍♀️

More like a cat toy size ball. Still a good toy.
I should have paid more attention to the size as they are slightly bigger than golf balls. The ones I was looking for are identical but about the size of a grapefruit. My dachshund has one and it is her favorite ball toy. That's on me though. These are more of a cat toy size ball. These do look like they are the same material as my pups larger one which is durable and fun for her to throw and bounce. The holes make it easy for the pups to grab and run quickly or catch in mid-air. I'm not sure how other small dogs would do but these are too small to play tug-of-war with my little girl and she is definitely not as interested in them as she is with her bigger one. I think we will donate these to animal control since I am sure they have some small dogs or cats that would appreciate these more than our picky girl lol. Still a great toy but just not the size she likes.

Nice, long lasting balls.
My dog is not an aggressive chewer and solely just wants to play fetch. As a small 8lbs dog, this is the perfect size for her. Typically these will dry rot after a few years of use. We do buy these so it’s a little bit less destructive while throwing a ball inside the house.

My corgis love these!
Perfect for corgi puppies. I always buy this brand for my corgis. It’s perfect for them and I don’t have to worry about broken teeth.
