Love these balls for my dog. They have a nice weight to them so you can throw them far. The material is very bouncy, so they do sometimes bounce over my fence, but they are very tough and not easily destroyed / very chew resistant. My dog is ~65lbs, it’s a perfect size for her, and she loves these and regular tennis balls the most. She is still able to squeeze it in her mouth, so it still has some softness / some give for her to enjoy.

Perfect toy for my corgis!

Playing fetch for hours

Size: Medium, Style: Medium (4 Pack)

Tennis balls with the hairs pick up so much dirt and then that goes right into my dog's mouth. These are cleaner, my dog loves them, and they are easy to find when my pup decides he's done and drops it in the lawn or the snow. They hold up well after playing hours of fetch with my border collie.

Built tough for puppies

Size: Medium, Style: Medium (4 Pack)

These are great, the bright color stands out in grass outdoors they bounce well on hard floors indoors, and they’ve held up well even after a couple weeks of a very chew happy puppy playing with them.
