We've had this for about six months and my 75 lb, 14-month-old German Shepherd pup LOVES IT. Her favorite is "Crazy Bouncing Mode." In fact, she doesn't care much for the normal mode. She chews it a lot - even drops it in her water bowl at times - and it's still going strong. This is a great purchase. It's nice hands-off entertainment. Do know that it is heavy compared to a normal ball - if your pup likes dropping it on the ground like mine does, it will land with a hard "thud," even with the included sleeve. Hopefully you don't have downstairs neighbors. Also know that the cover that goes over the charging port is removable and your dog may choke on it if they chew it in just the right manner. Definitely only let the pup play with it while supervised. All in all, great toy.

Bully proof?!

We have the cutest little pit/lab mix who destroys stuffed toys in about two seconds flat. It’s always a HUNT to find toys he won’t instantly shred. This brand has some of the best! They were in FiveBelow for a while and it was the only brand that stood up to him initially. He finally got through the first only after MONTHS so we bought a few back ups and they’re still going strong months later! They’re also not super heavy so these end up being the toys we play fetch with most often! 100% will be buying more in this line in the future!

Great Option

When this chew arrived, it immediately became a favorite. It seems sturdy and is soft enough to be dental friendly.

Love these!

My dogs finally chewed pieces off of these bones but it took forever for them to do it and they didn’t chew very much off! These are great and I will buy more!
