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.

Great for heavy chewers! Belgian Malinois Approved!
Color: E) 8-Pack 2.5" Balls (Yellow)
I bought these 6 months ago because my dog kept loosing his Kong balls. These were such a better price ball (but still had good reviews) that I thought I would give them a try. They are wonderful. After six months of chewing and chasing and playing with a Belgian Malinois, the two that I’ve gotten out are still in great condition. The bright color makes them easier to find, so none have been permanently lost yet.
They are bouncier and a little bit lighter weight compared to the Kong balls of the same size, which I honestly appreciate because my maligator likes to shoot them at my feet.
So far the material seems high quality and I feel safe letting the dog chew on it for hours on end.
The 8 pack was cheaper than 2 Kong balls. A great deal for a great product!!

Durable, high-bounce dog balls that hold up well to energetic play
Color: D) 4-Pack 3" Balls (Yellow)
The Chew King 3-inch rubber balls have been great for active play sessions. The rubber feels thick and durable, and the bounce is surprisingly lively compared to many standard dog balls. They’re the perfect size for medium to large dogs and are easy for dogs to carry, chase, and retrieve. After repeated games of fetch, the surface has held up well without cracking or losing its shape.
One thing that stands out is how easy they are to clean. Dirt and slobber rinse off quickly, so they’re ready for the next round of play. The bright color also makes them easier to find in grass or bushes compared to darker toys.
For longer life, it helps to supervise play if your dog is a very aggressive chewer, since these are designed more for fetch than constant chewing. Also, rotating toys every few days can keep dogs more engaged and extend the lifespan of each ball. Overall, this is a solid set of durable fetch balls that provide great bounce and reliable outdoor playtime fun.

toughest dog balls in the world
Color: E) 8-Pack 2.5" Balls (Yellow), Color: E) 8-Pack 2.5" Balls (Yellow)
best balls in the universe. I have a 70# pit bull and a 120# presa canaria. All the other balls I bought lasted maybe 3 weeks, I have had these for over a year and play with them and the dogs 5-6 days a week. They still look brand new, They seem like they will last a year or so and they are both serious chewers. A presa has a bite force od about 525psi, twice a pitty
