Cute for a puppy or small dog- not meant for chewers
Color: Octopus Purple & Blue, Color: Octopus Purple & Blue
I bought this cute squid two-pack as Christmas toys for two dogs, and they’re absolutely adorable. The colors are bright and fun, and the crinkle sound inside is very appealing especially to the puppy I was buying for. They are a little smaller than I expected, but I added a photo with my hand in it for size reference. The size ended up being perfect for our 12-week-old Irish Setter/Golden Retriever mix. He loves grabbing the tentacles and flinging it around. It’s easy for him to hold, shake, and carry, which makes it a great puppy toy. I also have a German Shorthaired Pointer, and it’s definitely not big enough or sturdy enough for her, she doesn’t really play with it. But for a puppy or small dog, it’s ideal. The Tupac is ideal, but losing one star just for durability and size.

Lasted longer than I expected! But Still going...
Color: Octopus Yellow & Green
My dog was hesitant at first, which was strange because he loves the squeaker toys. would smell them and then walk away (I think it had a manufacturing smell) but after a few hours of airing out the fight (Playing) was on! Lasted longer than I expected! the squeak was gone from one of them but somehow, he managed to get it working again. normally he would chew the guts out to get to the squeaking piece, but they are surprisingly both still in tacked! and also, he refuses to share with his big brother even though he has two of them!

Another one bites the dust!
Color: Octopus Purple & Blue
Good toy, but nothing spectacular. Took my 10 month old girl less than a day to kill the squeaker lol. Item is still intact meaning its not shredded but once squeaker dies she's pretty much done with it.

My dog's obsession
Color: Octopus Yellow & Green
My dog has been obsessed with these since he was a puppy. I started buying them in 6 packs. He chews is after each meal like dental floss and it's always soggy and gross. I keep an eye on the legs and throw it away when he begins to chew through them. One lasts him a couple months (80 pound Lab).

Great for treats
Color: Octopus Purple & Blue
We purchased this to keep our dog busy and engaged. He seems to enjoy it. We placed 1 or 2 treats in the tentacles and then loosely tie them. He can not untie them but can still manage to get the treats out. It amuses him for 10-12 minutes which is great. Only downside I can see is that the octopus is going to get grungy soon because of the treats and the treats and the constant licking to remove them. Not sure how it will washup but we will try. Very soft and decent squeaky sound.
