Good for night sessions
Size: Medium, Pattern Name: Pack of 1
Picked this up for evening fetch sessions and it’s been a win. It charges up fast, couple minutes under a lamp or in sunlight and it’s good to go, and the glow is genuinely bright, not the sad dim purple some of these put out. Makes it way easier to find in the yard at dusk, and the dog can actually track it.
It’s a little on the softer side compared to a regular tennis ball, but durable enough to hold up to my big dog, who is not gentle with toys. Still kicking after plenty of chomping and slobber. Fits a standard Chuckit! launcher perfectly, which is the whole point.
Pros:
• Glows brightly and clearly in the dark
• Charges fast from any light source
• Holds up well even with a big, enthusiastic chewer
• Fits standard ball-throwing sticks
• Great for evening or early-morning fetch
Cons:
• A bit softer than a regular tennis ball — a determined power-chewer could probably destroy it eventually
• Glow fades after a while, so you’ll need to recharge it during long sessions
• Only glows if it’s been charged, which is obvious but easy to forget
Tips:
• Charge it under a bright light or in the sun for a few minutes before heading out
• A flashlight works in a pinch if you forgot to charge it
• Keep it out of permanent fetch duty — rotate with a regular ball so it lasts longer
• Not a chew toy, even though it’s tempting to leave it with the dog
Five stars. If you’ve got a dog and a yard, this makes evening fetch actually doable.

Westies Fav
Size: Small, Pattern Name: Pack of 1
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.

Keep your dog active for hours
Color: Classic, Size: M 3.46 in (8.8 cm)
I buy 2 of these balls a month. My Boston Terrier is obsessed and rolls the ball for hours. It is made of a hard plastic so it is best to play with it outside.

Great for dogs
Color: Classic, Size: XS 2.75 in (7 cm)
Puppies and dogs love this. I have a bigger one as well so I wanted one they could fetch. This works perfectly for fetch.
