dog's ball
Theme: Football, Size: Large
Was too big and very heavy. Smaller would be good for my very large full male german shepherd. But he loves it. Too heave for smaller dog.

Durable
Theme: Football, Size: Large
I have a German Shepherd and a pit mix and they played tug-of-war with this. I’ve had it for about six months and it’s still holding up.

Not for heavy chewers!
Theme: Animals, Size: Medium
Didn't hold up well - but realized I didn't read that it was for "light chewers." Otherwise, cute design.

Soccer ball just for dogs
Size: 6 Inch Diameter, Color: Ocean Blue
I could say "soccer", and our shoodle would wag her tail ready to play soccer with a tennis ball so I tried out this real soccer ball with her. Mostly, she just wants to wait for me to kick it, playing defense, so she can chase it like the tennis ball. After that she wants to usually bite it or roll over on top of it as a way to secure the ball, but sometimes she will have fun pushing it around with her nose or paws. She still prefers the frisbee for play time outside since the frisbee is good for catching and for playing tug-o-war, but this is a good alternative that always gets her wagging with excitement. I wanted to get a regular 6" soccer ball for our shoodle, but this was a good choice for dogs for the durability and safety of the rubber material. The hexagons give the dog some grip to pick it up. The rubber is soft enough to grip and expel air when they do figure out how to grip it. The ball is designed to suck back in air when the dog releases the ball. - Durable rubber material ideal for dogs - Dog can squeeze out air to grip it - Ball fills back up with air after air is squeezed out - Can make more noise than a leather soccer ball - Noise is still tolerable when used indoors

Good for aggressive cheers. Reinflates everytime even when punctured
Size: 6 Inch Diameter, Color: Apple Green
I have an aggressive cheer that will tear apart anything. I bought this a few months ago and it is covered in puncture holes but it reinflates everytime. Best dog toy ever she loves it. I would buy a dozen of these. The medium size is perfect for my mini bull terrier. Big enough to not get completely in her mouth but small enough that she can still grip it to carry it around
