Indestructible
Style: Fetch Balls (Pack of 2), Size: 3 inch
These balls are indestructible! We have a lab and a lab mix and they CANNOT damage these balls. They love them for fetch and to just chew on them (slightly squishy, but NO damage). Best toys we have bought for them.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard
White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it.
Orange is easy to see in the grass at day
They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too
The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

A Totally Unique and Lasting Ball Toy Which Captures My Older and Previously Lethargic Dog’s Attention
Size: 3.5"
At about the time of my dog’s 8th birthday, I felt discouraged when I noticed a change in his playing habits and he seemed bored with most of his former favorite playthings. At a younger age, he played for hours until he exhausted himself, and then after a deep and lengthy nap he would resume playing with his toys.
His indoor playing time had decreased even though he was in perfect health. He does not have any arthritis, and he does not have any aches or pain, he was just mostly bored with his toys and after about 10 minutes of playing, he would walk away, stretch out and lie down. He seemed to have lost his interest in chasing after a ball, and I was getting desperate to find something new and completely different to end his daily lethargic existence.
These Gnawsome squeak and light balls have re-captured his interest as something completely different that he had never experienced with any of his other toys. Currently, he has several of these squeak and light balls and in two sizes, the medium 3.5” and the larger 4.5”. There are a variety of colors with different color flashing lights. Both the medium and the extra-large size are suitable for larger breed dogs like my Old English sheepdog. The large dimension guarantees safety that he will not accidentally swallow and choke, because they are too big to slide down his throat.
What makes this squeak ball unique is the addition of a flashing light, as this is something different that he had never experienced with any of his toys.
As he mouths the ball, a light inside the ball starts to flash with color. When he sees the flickering light he then drops the ball and he stares and watches and perks up his ears. When the flickering light stops he bats the ball around, grabs it in his mouth and tries to squeak and flash the light again. It’s obvious that the flashing light fascinates him and he enjoys the squeak sound as he mouths this ball. In addition, the soft flexible rubber spikes must feel good against his gums.
In the mornings as I struggle to wake-up and grab a cup of coffee, he is right there nudging my leg with his ball. He drops it at my feet, and starts running down our long hallway in anticipation of the throw and catch game. At night, it’s even better, I’ll turn off the lights and he can easily see the ball to catch it, and the ball lights flicker as it bounces against our hard tile floor.
I started his Gnawsome Squeak and Light Ball collection almost a year ago with both the large and the medium ball sizes. He has two Reds, two Greens, and one Blue scattered around our home because he carries and plays with them from room to room. Each color ball has a different color light. The Red ones light up red, the Green ones flash a green light, and his Blue one flickers with both a red and a blue light. The only color that we don’t have is the yellow, but I’m still hoping to get that color too.
I am impressed that they have all retained both the squeak and their flashing/flickering lights.
These balls are lightweight so they really go a distance when thrown, and the color NEVER comes off on our white woodwork.
This is one of the best dog toys that I have discovered, they are unique, durable and the squeak and flickering lights last through his mouthing, and normal playing habits. My dog loves them and they are his very favorite toys. In addition, and these light strobe balls may even work for a dog whose hearing has declined, because instead of hearing a ‘bounce’, the dog could just follow and chase the flashing light.

Great Toy!
Size: 3.5"
My dog loves it. The ball is not soft, that's why I chose it for my super chewer dog. The squeak pitch is a medium level. The ball fits comfortably in her mouth. I would say it's an average weight.
