These are definitely indestructible
Size: Medium
Both of my dogs can destroy a ball in a matter of minutes if I let them play with them (supervised) as is. Well not with these balls. They are the ONLY ones I have found that are 100% indestructible. Please only let your dogs play with these as a toy when supervised though. They go really far when throwing them, so both dogs get a good amount of running and exercise with these. I also bought these because they have the hole in the middle of the ball which is very important in the event that a dog gets one stuck at the back of their throat. This allows them to breath unlike those without this hold. It's an unlikely event, but as dog owners, we all need to be aware of this and educate ourselves on what to do if this SHOULD happen. This isn't a scare tactic, nor a reflection of this particular brand, it can happen with any type of ball. My two dogs are about 45ish lbs and the size is perfect for them, I don't want anything smaller than this. They love them. There is no annoying squeak. Really easy to wash after use. Some balls take forever to get the slimy saliva off, but these don't.

Balls

My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.

Nice set of balls
Size: Medium
The squeaker quickly became my dog’s favorite ball and has replaced the fuzzy tennis balls. My dog is a nonstop fetcher and these chuck it balls are durable and fun.
