Small for a medium
Color: Red-Blue, Size: Medium Size 2 (6"), Color: Red-Blue, Size: Medium Size 2 (6")
I got medium.. and it does not look like a medium ball.. it’s rather small. It’s pretty sturdy and my dogs went crazy for it but it’s definitely not the size I thought it was going to be 😂 my dogs chewed one strap within 5 minutes of having it but they’re dogs and that’s what they do lol. I bought this to be an outside ball for them! It’s pretty light but that’s probably because it’s small. Not soft? But feels like a soccer ball. It also had no smell coming out of the box. Also comes with a pump and an extra thing to put in the ball to pump in case you lose one. I like these balls, I expect them to be chewed up because that’s what I bought them for! Fun for my dogs and they are! But the size… it is not medium and that’s the only reason for 3 stars 😂😂😂 Other then that I recommend, your dog will definitely love this! Inside or outside playing! Alone or with another dog!

Great toy for a GSD
Color: Blue Gray, Size: Extra Large Size 5 (9")
My GSD loves to grab the flaps and shake her head with the ball bouncing of the side of her head. This is her favorite toy. I thought she would puncture it but it has held up great since she likes to grab the flaps rather than biting the ball.

Great, durable toy
Color: Blue-Red, Size: Extra Large Size 5 (9")
I’ve had this toy for a while now and my dog absolutely loves it. I frequently bring it to the dog park with us and it’s also loved by other dogs. The ball is pretty durable. My dog is not a big chewer but other dogs that play and chew on it haven’t been able to pierce it yet. The handles are sturdy and also still intact. Overall a little pricey but in my opinion worth it.

Best ball ever!
Color: Red-Blue, Size: Large Size 3 (8"), Color: Red-Blue, Size: Large Size 3 (8")
Oh my goodness. My cane corso (15 mos) LOVES this ball. It’s easy for them to pick up because of all the little handles sewn into the ball. It’s easy to throw as well. The only thing is he likes to chew them off if he gets free time with the ball. The ball itself is very sturdy. highly recommend, and I’ll be ordering more. We play with this every morning and he’s so excited to take it outside.
