Perfect squeaky ball. Dogs love them. I love that they're durable and their thickness aids their durability. My Great Dane will play alone for hours with a ball.

Excellent Pee Pad Holder for Indoor Dog Training
This pee pad holder is very practical and works great for indoor potty training. The non-slip silicone material stays firmly in place and doesn’t slide around on the floor. The raised edges do an excellent job preventing leaks and protecting my floors. The magnetic clips hold the pad securely, even when my dog moves around a lot. Overall, it’s well made, easy to clean, and makes puppy training much less messy.

Best choice
This pee pad holder has been a lifesaver for indoor puppy training. The 24" x 24" size fits standard pads perfectly, and the non-slip silicone keeps everything in place. The raised, leak-proof edge gives great floor protection, while the four magnetic clips securely hold pads without tearing. It’s easy to clean, durable, and looks neat at home. A practical, well-designed tray that makes potty training cleaner, easier, and far less stressful. Highly recommended for apartment owners and busy pet parents.
