Best ball for retrieving ever
Size: Medium, Style: Medium (4 Pack)
I have been using a ball launcher to exercise my Border Collie. Up till now I have been using the launcher to throw tennis balls. Even with the launcher I can only throw the balls a couple of hundred feet. These balls go MUCH further. I am using a steep horse pasture to throw the balls and I have to make sure that I don't launch them past the fence at the end of the pasture. I think the thing that makes them go further is their weight combined with a smooth surface. They also have incredible bonce. They hit and just shoot way up into the air. Also, the tennis balls I was using were green. In my horse pasture they were easy for the Collie to miss since they blended right in to the grass. These balls with the orange with blue stripes are far easier for the dog to find. It's really hard to tire out a Border Collie but these balls do the job.

Great fun for retrievers
Size: Medium, Style: Medium (4 Pack)
Great durable balls. Use these with or without the thrower. Lab puppy loves to play fetch and these are easy to spot in the yard. Our neighbor has 2 pit bulls who also plays with them. Will buy them again if need be.

Perfect ball for dogs!
Size: Medium, Style: Medium (4 Pack), Size: Medium, Style: Medium (4 Pack)
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.
