It doesn’t stop leaks from the pee pad.
Size: X-Large: 28" x 34"
I’m trying to figure out how not to have leaks occasionally. I’m going to call the company to see if there’s something I should be doing.

Great toy to play fetch with the dogs.
Color: Black/White, Size: Large
These balls are a great dog toy to play fetch with your dogs. This not the first ball I have gotten for the dogs. Just the right size and weight for medium sized dogs. I have less concerns about them possibly choking on these soccer balls versus tennis balls. So I can leave them out for them to play with. The are easy to inflate using the included pump. My only concern is the durability of the straps as my dogs have almost torn off one the straps of the previous ball I purchased.

Dog parents; buy this now!
Color: Black/White, Size: Medium
A must have for my pup! I have bought this at least 5 times. She eventually pops them and I need a new one. It's an amazing toy that she can thrash and we can play fetch with
