Great buy
This pee pad tray holder is a game-changer for indoor puppy training. The silicone construction with four fixed points keeps pads secure and prevents shifting, so my puppy stays on the pad instead of having accidents on exposed floor areas. The 23x23 inch size accommodates standard pads perfectly, and the raised edges contain liquids effectively, protecting my flooring from stains and damage while making cleanup quick and easy with just a wipe-down. The stable grip ensures the tray stays in place even with active puppy movement, and the design is sleek enough to fit unobtrusively in my home without looking like obvious pet equipment. For the price, this is a practical investment in housebreaking success. The tray has significantly reduced messes on my floors, made training more consistent by containing accidents to one designated spot, and saved me from extensive floor damage that would have cost far more than this simple solution.

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off.
One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again.
If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.

My dog LOVES this ball
Size: Medium, Size: Medium
Does your dog destroy tennis balls in seconds?
Yes? Then your dog NEEDS this ball!
It's squishy like a tennis ball, fits in ball launchers (even the cheap ones) and bounces when it hits the ground.
My dog has been literally playing with this ball all day and not a single mark on it!
The only bad thing is that it does not float.
Definitely worth the money!
Put it in your cart!

Perfect for ball demolishers
Size: Medium
The dogs love the chuck it brand. I don’t know what it’s made of but they go crazy over them. Will not play with another ball. Wonder if it’s “laced” with an addictive scent. Have pits. Very durable. Not able to chew to pieces. Last for about 6 months before there is a small break. I keep a back up because when the ball goes missing the house is in chaos. 😆 🤪
