Best Westie ball ever, my dog loves this ball. Exactly her size! 3" tennis balls are too big & she rips the fur off. this silicone-ish ball has no fur & is 2&1/2 " We have 2" balls from her electronic ball laucher, but she still loves this glow in the dark best!

Best dog ball in the world!
Size: Large, Pattern Name: Pack of 1, Size: Large, Pattern Name: Pack of 1
My dog is singularly obsessed with playing ball. He would drop a steak to chase a ball. (He'd return to the steak, but not without the retrieved ball. He's not an idiot.) He makes dangerous leaps, crashes into trees, and runs fast enough to catch thrown balls before they even hit the ground. Since he doesn't care about his own wellbeing, it's my job to protect him as much as I can. And a lot of balls are hard enough to cause him pain or dental damage when he mistimes a catch. Enter the ChuckIt Glow Ball! The minute Cowboy got his first Glow Ball, he no longer had any interest in the dozens of tennis balls scattered around the house and yard. If I took the Glow Ball away and instead threw a tennis ball, Cowboy would run to retrieve the ball, then return without it and begin looking all over the house for the Glow Ball. The Glow Ball is tough enough to survive Cowboy's big, sharp chompers, yet it's soft enough to do no harm when it hits him in the face. The glow feature is a huge bonus, too. Cowboy gets distracted by chipmunks and squirrels when we're playing, so he sometimes can't remember where he dropped the ball to pursue the interloper. If the ball was exposed to enough light before it was misplaced, it will be easy to find once the sun goes down. (Otherwise, Cowboy always finds it eventually.) When I'm feeling nocturnal, I'll put the ball under a light for a few minutes to activate the electrons, then treat my boy to a middle-of-the-night game of fetch. I was so happy to see these on sale, I bought a lifetime supply for my pantry. The size guide seems accurate. ChuckIt recommended the large size for a dog of Cowboy's weight and that size is perfect. Highly recommended product.

Great for our Lab!
Style: Classic + 2pk Ball, Size: 26in
Our Lab loves playing fetch and this is a great product to assist doing that. Great for open field, football-soccer fields, just any large open space. Another great use is scooping the ball up with ease.
