Total waste of money
I wouldnt give it one star but had to to leave a review. Just got these balls September 8, 2025. As of today we are on our third ball, September 13. My dog only used in field for fetch. He never layed down and chewed on it. The inside of the balls came apart. I pulled off felt to show where. The ball is otherwise intact. Never had this happen to any ball I ever bought. I researched and looked for good reviews even off Amazon because my dog is a border collie and loves to fetch. This is a huge waste of of money and bad for environment

Does the job
I do like that they come in bulk and that they weren’t too expensive but I definitely don’t think the quality is that high and they’re very easily falling apart but that’s probably because they are cheap. if you have a dog that is a they will get it into little pieces very soon after they have it. So I’ve had to put them up when we are done.

Not durable
Why did you pick this product vs others?:
I'm giving it 2 stars because these balls are not durable. They also don't bounce well. My dog cracks the seam easily. I will use them, but won't be purchasing again.
