Great for 22 pound mini schnauzer/mini greyhound mix
Color: Pink
I have a dog that is half miniature schnauzer and they love to sniff and snuffle. He is enjoying this ball. I put the little freeze dried liver cubes in it and he will play with it until he gets them all out, and maybe keep playing for a bit. I can't give it 5 stars because I don't know quite how I'm going to clean the inside of it. I can't speak for how well it cleans his teeth because he hasn't had it that long. It is sturdy. He's a 22 pound medium size dog and I'm confident he cannot chew it to the point of destroying it. He's barely made a scratch on it so it may break down over time but it's not something a small or medium dog should be able to chew through the first day. He's had it about 2 weeks and we use it every day and it's holding up very well. It's not interesting enough to him to play with it without treats in it but he rarely plays with a toy unless I'm actively playing with the other end of the toy or throwing it for him to chase (part Italian greyhound too so he does like chasing) but he will get excited when he sees this ball as he knows treats are going to be in it. This one is a good size for him and he can pick it up with his teeth. (This is the hot pink one with the blue ball inside) Definitely worth the price if I can figure out how to sufficiently clean inside of it. So far rinsing with warm water seems to keep it hygienic. It's silicone so everything pretty much slides out. I wouldn't put any moist treats in it though. It's quiet. No squeaker, but he has plenty of toys that squeak and we didn't get it for that. It definitely appeals to his sniffing and snuffling instincts.

Quality product
Color: Blue
Great toy but the holes are very large for the snacks so they fall out easily. I have a toy poodle and it was to large for her, it seems like it is made of good quality materials and would be great for chewers .

No match for 3 month old puppy!
Color: Blue
I was really hopeful this would last a while, but 5 minutes out of the box and my 3 month old puppy has chewed two chunks out of the blue part already - seems this is too soft for puppy teeth, and it specifically claims to be good for puppy teething. 5 minutes of play is not worth paying for. Maybe if the material had been more substantial, this could have been great for high activity level puppies. My pup had no trouble carrying it around, so it wasn't too heavy, and it was easy to play fetch with as well. For reference, my pup is a mixed breed - labrador, poodle, newfoundland.
