Saving My Floors
Size: 28'' X 34'', Size: 28'' X 34''
Omg, what a game changer. My pups like to destroy the pads whenever they get the chance to. With this they still try but never succeed. I will say that it can be a little sturdier as the handles are a little flimsy, but I manage and it does the job. It's very easy to use when I change the pads and I use 2 pads for coverage. I just placed it where I usually place their pads and it fits right in the spot. They are trained to go outside but on rainy days this comes in handy. To save my floors it's definitely worth the money spent.

Durable. Squeak doesn't last forever with my aggressive chewers but crinkle does. Best balls.

Balls
Size: Medium
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.
