Good for Teething puppies
Color: Teething Stick
After getting my fingers chewed and bitten by my new foster - 8 week old Yorkie , I was desperate to find good teething toys. Fortunately this one arrived quickly. Turned out to be very good for teething puppies! Charlie loves this cooling stick. Once it’s frozen, the cold really seems to soothe his sore gums. The icy part doesn’t stay frozen for long, but it works so well that I bought a second one to keep ready in the freezer while he’s working on the first. Even after it warmed up, he still enjoyed chewing on the soft stuffed part and the tentacles. The product card says not to use it as a chew toy, so supervision is a must, but it held up just fine so far. Overall, this has been a big help during the teething phase — short-lived when frozen, but very effective while it lasts! And worth every penny to save my fingers from being a chew toy.

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.
