Good quality
Color: Ultra, Size: Large, Color: Ultra, Size: Large
Great quality. I purchased for my daughter’s dog who destroys all toys. This toy holds up. I didn’t realize it was a large and the chickit stick she had was a medium. The large ball ended up working out good for playing inside the house. The dog likes it a lot.

Please read!
Color: Ultra, Size: Large
This dog ball is so useful! We have a large property and we use the Chuckit! thrower with the ball. The color and material of the toy is very high-quality and lasts for a long time. We have been using the Chuckit! brand for a long time now and we love their dog products! It is a good price and we buy replacement balls like once or twice every 6 months because they keep getting lost in bushes or trees 😂 After some time the color of the ball gets washed out and since our dogs are aggressive chewers, one of the balls we got broke and split open, but it was still usable! The reason that one broke is because we had it for a HECKA LONG TIME! It has no squeaker so when your dog has the ball it wont make any loud and annoying sounds. It is easy to pick up with the thrower and it seems durable and sturdy enough to last them a few months. I don't recommend as a cat toy because this ball is specifically designed for dogs. But is your cat likes fetch i guess it could work! The ball is soft enough to not be hard as steel, but is sturdy enough to not break immediately.

Awesome quality balls -- my dog loves them!
Color: F) 3-Pack (2.5" Balls)
Love this 3 ball set and variety and quality. These are the 2.5" size, similar to a tennis ball size give or take. The fun citron yellow one is the thickest + heaviest, very bouncy, and tough. The blue is still tough but not as thick or bouncy, a bit more flexible. And the clearish one is the lightest/flexible and is glow in the dark [although we haven't tried that part yet]. I have a 7month old 40lb girl who is becoming like a power chewer on some things -- but hasn't done that with these. She can play, mouth them, chew them, not even one knick or anything. Yes! The citron and blue one we leave out all the time in her little toy box. They have holes in the middle and have used them to hold thinner bully sticks and other treats. The blue one is fun to put smaller treats inside that she can work out like a puzzle. Obviously they are fun for fetch! We leave the other up and only get out when we can play with her because label said it is not a chew toy so we didn't want to take chances. Overall super fun and cool and good quality, human and dog approved LoL. ***We ordered the 2 set of 4" balls, blue and purple [they are same consistency of the blue ball] and love these too! Very fun and good at using with treats the sticks too, plus these don't get lost under sofas and furniture like the smaller ones, a big plus.

Glow and play - pups favorite!
Color: A) 2-Pack (2.5" Balls)
I can't say enough good things about this glowing fetch ball! It's perfect for outdoor play at night—my dog loves chasing it in the dark, and the bright glow keeps the fun going even after sunset. What really impresses me is the quality; this ball has withstood my pup's enthusiastic chewing (and believe me, he can demolish a regular ball in seconds). It’s durable and built to last, making it a fantastic investment for any dog owner. If you're looking for a fun nighttime activity, this glowing fetch ball is a must-have!
