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

Dog approved for fun, human approved for durability for the price.
Size: 8 Inch Diameter, Color: Orange
This has been my dogs favorite outdoor toy for years . I love these because they are durable and won't deflate when bitten or when carried around in their mouth.... no matter how many holes the dogs put in them. We leave these outside year round even in Minnesota winters. It is strong enough to hold up yet soft enough to be safe on their teeth. Now I do want to say although it is really durable it is not indescribable. IF you have a heavy chewer or a dog that loves to destroy toys, they would need supervision with this I think. My dogs don't try to chew this up but they do wear out over time. We replace it every 2 to 3 years on average. Definitely dog approved and recommended in my home, and human approved for cost and durability. I hope your dogs love it as much as mine do.

Best ball for dogs!
Size: 8 Inch Diameter, Color: Red
This is the best quality and long lasting ball for dogs. It's soft enough to kick and durable enough to where they can chew and chew and it will not lose It's shape. We play hardcore everyday for months and it holds up. Never have to worry about chunks falling off and peeling. Border Collie approved!! Also, $8 cheaper off amazon VS pet store or pet store website. You'll know when it has to be replaced once you have to manually re-inflate with your hands but thats after many many months.

GOOD BALL
Size: 6 Inch Diameter, Color: Apple Green
This is my second time buying this ball for my blue heeler, and it is easily his favorite toy. It is very sturdy, especially for hard-playing dogs, and handles rough outdoor play sessions effortlessly. The design is brilliant because it does not go flat, yet my dog is still able to bite it and get a good grip on it. It’s the perfect combination of being tough but still flexible enough for a dog to enjoy carrying around. For comparison, our first ball finally stayed flat after a solid 2 months of non-stop, hardcore playing, which is a massive win compared to other toys he destroys in minutes. If you have an active, high-energy dog that loves to play rough, this ball is highly recommended!

Best Ball ever! Aussie is obsessed
Size: 6 Inch Diameter, Color: Orange
I will never buy any other ball!!!! I bought the 8 inch which my crazy Aussie liked. The 6 inch one he won't stop carrying it around. his face use to be so sad when he would pop other balls. This one deflates and fills back up instantly! He chases it and chews on it. We gone through a lot of balls, but this is going to be a staple in our house!
