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.

Good squeak and bounce
Size: Small Set of 8
My friend's smallish dog can make them squeak and they have a good bounce. The dog loves them. We returned another brand that did not squeak. They're colorful and are durable.

Excellent durability!
Size: Medium Set of 6
I’m impressed with how durable these balls are! The rubber is nice and thick and tough, so my dogs have been unable to rip them apart yet. The spikes help clean their teeth when they chew, which is a plus. After weeks of use, the rubber is not sticky and does not smell. They haven’t lost shape or bounce. The size is perfect for my large shepherd husky dogs, as well as my medium sized Heeler. The loud squeaker in 2 of them has stopped working, which I’m not sad about. As a matter of fact, I’d give 10 stars if all of the squeakers stopped squeaking, lol! The package of 6 balls was a great value!! Will definitely buy again.

So much fun
Size: Large Set of 3
The dog and my wife love these. The spines keep your the drool you have to touch to the minimum. Very durable for a dog that loves his toys and destroys them. Squeak is fun but got a little much. Just stabbed knife into the squeezer hole and silenced them right up - still kinda squeaks, just without all that high pitch goodness.
