Spiked Ball = No Slime!! ☺️
Size: 2.5" (Small Dog), Color: Blue+Orange+Green
You will lose these balls before your dog could destroy them. Very sturdy for the price. The spikey ball style means your hands won’t get slimed when your dog drools on the ball playing fetch. Great fun colors.

Durable but to hard to chew to make squeak.
Size: 2.5" (Small Dog), Color: Pink+Red+Yellow
Nice and squeaky but a little too hard for my 25# Cockers to chew on...may be the spikes.

Used for tense muscles
Size: 3.5" (Medium/Large Dog), Color: Set of 6
I don’t use these as dog toys. I use them as therapy balls. You place it on an area of tension and lean on it. Works like a charm to take pain away!

An absolute must have in our house
Size: 2.5" (Small Dog), Color: Blue+Orange+Green
We have a couple of miniature Aussies. One is more of a snuggler, but the other is addicted to playing fetch and these balls are her favorite! Perfect amount of bounce and squeak. Perfect size for her mouth and a great value. Very durable too.
