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!

My Dogs Favorite for throwing
Color: D) 2-Pack Lattice (3.25" Balls), Color: D) 2-Pack Lattice (3.25" Balls)
We brought our new adoptee home end of July, and I quickly had to find him replacements for his tennis balls because those balls are inherently abrasive and our yard has sand which gets in the fuzz and makes them extra abrasive and they were already causing tooth wear (our previous shepherd chewed tennis balls like gum for a week after his adoption, wore his teeth tips enough I noticed and I took them from him too but this guy didn't like the hand me down replacement, it was too big for his preference so I had to hunt down different ones for the current dog).
I tried the glow in the dark Chuk It ones, but he doesn't like to carry them, or the smaller regular chukits... My current dog prefers these web style ones. I like glow in the dark stuff and it makes them easier to find in the evening or over night (if you have night adjusted eyes and not a lot of lights in the yard these are VERY glowy at night). Now I know he likes them I am thinking winter is coming and I may lose the glow color in the Michigan snow, so I'm here to order some in some in non snow camouflage because I want to be able to play in the winter without as much groping for hiding balls (literally he will chase and then snub any other balls in the yard I throw except the huge jolly ball but that isn't a fetch type ball, its a thrash toy. these are the only ones he will actually return for me to swap and throw indefinitely).
I included video and a picture of them at the local beach. They float with enough above the water for maybe a few ants to use them as a flotation device, but take a bit of time to come to the surface when they splash down. I think brighter colors will help make them easier to find in the water as well as the snow.
I think my dog likes them because the webbing design makes it easier to grip, even when slobbery his teeth can get a hold in the gaps (so can fingers haha) without slipping too badly. They also compress almost flat and boing back into shape and seem to be durable over at least 6 weeks of summer living in the yard, so far so good. They don't have a huge amount of mass so they don't whip super far but if you get a technique down you can get very reasonable distance on throws. He doesn't gnaw on them, so I can't speak to resistance to actual shearing attempts with teeth, just grab and chomp for fun, then holding in his mouth.
My dog weighs about 68 lbs (we are trying to gain a bit), he is a German Shepherd, and this size fits him well (can't remember which size I got but usually Amazon shows what size the reviewer got near the title of the review. They're big enough I'm not worried he will accidentally swallow or choke on them, small enough his mouth fits them comfortably, his grip is secure because of the gaps, and he loves them. I suggest get two at least unless your pooch is super good about dropping it and letting you pick it up. With two, I can whip a ball, find the one he just dropped, and by the time he is back, I have the other one in hand. He knows I won't throw it unless he drops the one he just returned (I will wait for him to remember this), and this makes it way easier to play thow and bring it almost back (he often drops it at speed when he is nearly back to me so it rolls past me) without playing chase me for the toy... and makes reinforcing Drop It as an safe thing to do, like he isn't going to lose out if he drops the fun ball in his mouth, I have the second ball to mark (say YES!!! when he drops it) and immediately reward by throwing the ball I already had... he loves them enough that he thinks other balls are stupid so I don't want to throw a less cool ball to exchange for the cool ones haha
Anyway hope this was helpful, Im off to order some of these balls in brighter colors for lake and snow visibility.

Fun Glow Balls for Night Play, Great Value
Color: A) 2-Pack (2.5" Balls)
The Chew King 2 Piece Glowing Fetch Balls are a solid, budget-friendly alternative to Chuck-It glow balls. While my pups prefer the mouth feel of the Chuck-It balls, these still provide bright, visible fun for dusk or nighttime play, and can even be used indoors with a flashlight to get the game going.
Durable, glowing, and engaging—a good option for evening fetch sessions which always insures that our pups get a great night of rest.

Durable, Perfect Size, and Glows
Color: A) 2-Pack (2.5" Balls)
I bought these for my 23 pound Bojack (Boston Terrier/Jack Russel) mix and he absolutely loves them. He’s an aggressive chewer that has destroyed Kong toys. This ball has just enough flex or give in it that he can’t tear it apart as it compresses in on itself. After about 6 months it started to wear down and tear a bit by the hole so I just tossed it and gave him the other one. I’ll be buying more of these as they wear out over time.
