Fun dog toy
Size: Medium(6")
Great ball, easy to use, sturdy toy, and fun toy that dogs love. Only a 4 star as I wish it was a little bit bigger and with more handles.

Nice ball w/straps to grab for ur dog to carry the ball.
Size: Medium(6")
She’s afraid of SO many things. Gotta give her more time. From a hoarding group…so, no socializing. Time will tell. Very nice ball w/ tough straps to grab hold of & carry it.

70lb dog loves this kind of ball!
This is my dog's favorite style of ball! I have purchased others before, first from a local farm supply store and then others from Amazon, and this ball is of comparable quality to the others! The multi-tag design is great for my dog who love to tug and also to throw toys for himself. It's still inflated for now, but I'm under no pretense that it will stay that way forever. Part of the enjoyment my dog gets from his toys is in their destruction, and while we haven't hit that phase yet I'm sure it will come. This ball is great for medium to large-ish dogs who enjoy a ball that is kicked, thrown, or tugged!

So much fun
My dog is obsessed with this. It comes deflated and you have to pump it but it only takes like 30 seconds to pump. And it comes with the pump which is so convenient! It's nice because you can leave it a tad deflated so your dog can grab onto the ball part if you want. My dog has bitten it a ton and it hasn't popped or deflated yet so it seems sturdy. I like that there are multiple handles because not only does it make it easy to play tug o war but also then you can have multiple dogs playing with it at once. Has held up good over the past week and a great source of entertainment! My dog is about the size of an aussie for reference and it is perfect size for him and small enough for him to carry.
