Nice toy, but maybe not so durable
This is our second one of these, which really speaks to how much my dog loves it… it’s cute and just the right size for my Vizsla. She absolutely loves playing with it… it’s chewable and has a nice squeaker, but I’m not so sure of its durability. Our first one lasted about a month, and this one just a couple of weeks. The stitching at the tip seems to give away first, then the find. Sadly, you gotta throw it away when you see the first signs of the stuffing.

Easily torn apart but still fun
Color: Orange+Green
This is not the toy for your dog is they like to rip them apart. That being, my sister’s dog loved these as his gift. He did tear them apart pretty easily but he enjoyed every moment of it and they were his comfort toy for at least 3 months. The colors are great, the size is perfect for tug-o-war and tossing around. The squeaking noise is loud and grab the dog’s attention easily. My sister’s dog is a corgi mix so he went ham on playing with these.

Will buy again!!!
Color: Blue+Purple
I bought a set of these toys for my 30 lb black labs (mixed breed). They are normally very aggressive chewers, and as a result, these dogs are difficult to find toys for. They destroy pretty much everything except for those very strong rubber toys which are not as much fun for them to play with. So far, these toys have lasted us 2 days and counting which is quite an accomplishment considering their soft toys typically last about 10 min. or so before they start eating the stuffing and pull the squeakers out. Between the plastic noises from the tenticles and the squeakers my dogs have just been having the time of their lives. We have to confiscate them at bedtime so we can sleep! Even though I'm positive these toys will not hold up for much longer because of their chewing habits, it was worth the money to splurge on something fun for them to get so excited to play with. I intend to replace them occasionally as long as we continue getting at least a couple days of use out of them. If your dogs are less aggressive chewers then you should definitely give this toy a try!

Great toy
Color: Orange+Green
My dogs loved getting these for Christmas! They each have one so they don’t fight over the one toy. Value for the money is good. They constantly play with them and the portability is great too. My one dog, Poppy, drags the orange one outside all of the time

Fun toy for the family dog but the puppy can pull the crinkle paper out
Color: Orange+Green
I would have given this five stars because my 5-year-old Australian shepherd border collie loves it shakes it tugs with it. It has held up great until we got a puppy and then the puppy pulls out the crinkly paper which looks just like a clear plastic wrapper so that's not good this is our second time ordering these. The first time was for my current dog and the second time when we got the puppy so he had something to play with too.
