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 toy to play fetch with the dogs.
Color: Black/White, Size: Large
These balls are a great dog toy to play fetch with your dogs. This not the first ball I have gotten for the dogs. Just the right size and weight for medium sized dogs. I have less concerns about them possibly choking on these soccer balls versus tennis balls. So I can leave them out for them to play with. The are easy to inflate using the included pump. My only concern is the durability of the straps as my dogs have almost torn off one the straps of the previous ball I purchased.

Dog parents; buy this now!
Color: Black/White, Size: Medium
A must have for my pup! I have bought this at least 5 times. She eventually pops them and I need a new one. It's an amazing toy that she can thrash and we can play fetch with

Westie LOVES this toy
Color: U.S.A, Size: Medium
My pup (Westie) adores this toy. This is actually our second one. The ball itself is resistant but the straps will be obliterated. Would definitely recommend! Totally worth the price!
