My GSD's Emotional Support Balls
My GSD has three of these and they are undoubtedly his emotional support balls. I bought these so that the medium ones wouldn't get stuck under our couch and make him spiral. He takes one everywhere, it keeps him company in his bowl when he's eating, it gets dropped in my shower, it goes potty with him, on walks, it falls out of his mouth when he falls asleep. These are the equivalent of a GSD pacifier. Best Purchase I've made hands down. Plus they don't get stinky after being constantly covered in dog drool and if they get dirty/ muddy/ hairy a decent rinse will do the trick . They last a LONG time with my super chewer, they are firm enough so that when he gets a good chew on it it doesn't fall apart. He has endless hours of obsession logged into these balls.

Great Durability
Even my heavy chewer GSDs haven’t destroyed them…yet. Easier on your shoulder if you buy the ball thrower.

Dog loves this ball.
Great ball. The dog loves chasing it and it bounces in different directions so she can’t anticipate where it goes. So far she hasn’t been able to chew through the ball. She Is a medium sized dog.

Durable, bouncy, absolutely loved!
My dog, bless her heart, goes absolutely bonkers for these balls. I swear she knew what was in the package before I even opened it she was right there trying to open it for me. These are GREAT! We take them to the park with the Chuck-it Stick, to the river for some water fetch, and anywhere as her “reward” for being calm and obedient. Beware though, they sure can BOUNCE. She dropped one of these out the car window (we were going 20mph in a residential area) and even after searching for almost 10 minutes I could not find it. They can withstand her super-chewer mouth with no visible damage. I highly recommend!
(Photo is of the tennis ball version of this product, she doesn’t sit still long enough for a photo of the rubber version).
