An instant favorite for my one year old pup!
Size: Small, Size: Small
I came across these randomly while looking for presents for my one year old 10lb chi-mix. I gave her one to start with just to make sure it wasn’t flimsy & she wasn’t going to destroy it because she is definitely a chewer. She was instantly OBSESSED! These are now her most treasured squeakies. They’re the perfect size for her too and I’m happy to say they’ve held up well to her pouncing/jumping on them constantly. They’re definitely not quiet but we get an absolute kick out of watching the way she plays with them. If I could give 10 stars I would. Almost two months later and the novelty hasn’t worn off to her. I’ve saved them to my lists just in case we ever need to replace them for any reason. I’m not sure she’ll ever love a toy as much as these

Squeak is not super loud! Family fun!
Size: Small
My small dog loves these toys. He detects them the very moment they enter the house, even more if the package has been opened. I used to give him one at a time because he would favor the newest one for quite a long time. Now he sniffs them out no matter where I store them.
The squeakers have fallen INTO the toy rather than going down his throat, and they're rather difficult to chew out of place. They do collect quite a bit of debris and hair from the floor, so a good rinsing is needed sometimes. My little 13 lb terrier mix loves them with and without squeakers. For this dog, it's the best toy we've found.
We can do a little tug of war with it, throw and fetch, and he's even copied various ways we squeak the toy. I don't know what your pup will think, but these seem the most safe, longest-lasting, most engaging toy he has. If we step on it by accident, he always comes running for some fun.
Let us know if you have come up with a new game! We call one "Puppy Puzzle" where we bury it under various objects such as blankets, boxes, and find ways to squeak it when he can't quite find it. It's a daily ritual. We also like to be creative when we introduce new ones by hiding them, or mixing them in with older ones.
For us, it is a family interactive toy. He loses interest faster when playing alone. Plus, because of its size and random bouncing directions, it often gets out of pup's reach under furniture or in spaces too small for him to get it himself. We like playing with our dog, so it works for us. We've tried other toys with similar sizes and appearances, but for whatever reason, this is the one that has become part of daily life, and there appears to be no boredom yet after 2 years. Love!

Good For Heavy Chewers So Far
Color: Onyx Black - Most Durable
Solid quality. My Doberman is a power chewer and I am looking for a toy that he can't destroy in 2 seconds. If a ball lasts more than an hour it is a miracle. It has a sturdy design and is more heavy weight than the other "non-destructible" balls he has. He has only had his ball for one day so we will see how long this ball lasts him. It is the size of a tennis ball, firm, little to no bounce, and seems built for heavy chewing.
