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.

Perfect for my dog
Color: Blue Puppy, Size: Medium Size 2
My dog (16 lb) LOVES to whip her toys around and throw them in the air to chase after them. This is the perfect toy for her to play outside by herself. I would repurchase for her over and over again if needed!

Pup loves this!
Color: Blue Puppy, Size: Medium Size 2
My pup loves his soccer balls. These are very durable although if you have a dog that doesn't grasp the concept of using the loops/straps to carry it, teeth could puncture it. They are a good value for the money if your dog likes to chase the ball, I get the smaller size ball for my dog (medium dog). They come with a pump but if you have a bicycle pump or a battery operated pump, it will fill much faster. Ours stay outside and even in the winter, they hold up well, just need a bit more air occasionally to keep it pumped up.

Well that didn't last long!
Color: Blue Puppy, Size: Medium Size 2
He loved it for the 15 minutes it took to destroy it! Cute design, but the material was thin enough to penetrate with his teeth and it was all over in a very short time! He still carries the carcass around and tries to play with it...it's sad. Definitely not for strong chewers.
