The balls were a bit too big for my 6 month chihuahuas:/ they are as big as a tennis ball so puppies didn’t like nor play with them

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.
