Nice and bright
Color: Orange, Size: MINI 1.75" - 4 Pack
These are great to fit the ball shooter I use with my dogs. Color orange makes it easy to find in grass or dirt. Problem is I have a chewer. He loves to chew on the ball and eat the orange fiber. So, the balls get wrecked and I have to replace. Gets costly. I wish they made this same size ball without the orange furry tennis-ball like covering. Maybe the toys would last longer.

Safe for dogs
Color: Green, Size: Regular 2.5" - 4 Pack
Much better for dogs than used/dirty tennis balls. Worth the money for safety.

Easily breakable coating/fur
Color: Pink, Size: MINI 1.75" - 4 Pack
I wanted to love this item but sadly my dog really messed up the coating/fur on these balls so easily, other than that great product but with her being a puppy I got these smaller ones for that reason and I’m absolutely scared of her destroying things and getting stomach issues, so it’s just not worth it to me.
