Pillow is Unsafe
My eleven month old Cavalier, Lacey, loved this heartbeat pillow for about two hours. She carried it everywhere. Then she located the velcro opening. She ripped it open, pulled out the stuffing. I stuffed the heart in the bottom but I cannot locate it in the pillow nor have I found it anywhere in my home. Velcro closure is not enough to keep a curious puppy from figuring out how to open the pillow. Would I recommend this product: No I do not recommend this item. It was a total waste of my hard earned $. The closure needs to be reworked/improved. As it is now, do not leave your puppy alone with this heartbeat pillow because it is not safe! The only positive is it kept Lacey from barking for two hours while she played with it. I cannot attest that it would have helped her severe separation anxiety and yelping every time I leave the house. Lynne Weston Amazon Customer

my dogs love these! their new constant companions!
When I first opened the box and saw these three octopuses, I thought they looked a little anemic, but looks can definitely be deceiving because my dogs love them. We try to be really careful about the toys we buy because one of my dogs swallowed a squeaker in the past and had to have surgery. Ever since then, we've been really mindful about what toys they have and making sure we're watching them when they play. I have to say these have been great. My dogs carry them everywhere. They take them outside, bring them back inside, and I've had to wash them multiple times because they are so loved and so well used. For some reason, my dog who is a constant chewer and destroyer of toys has not chewed through these. They feel relatively tough, especially considering how lightweight they are. They do have a squeaker inside, but they also have something crinkly in them that makes noise when the dogs are running around and playing with them. My dogs seem to love that. My dogs also look super cute running around with the octopus legs hanging out of their mouths. Fun product!

Great toys for dogs
I received these octopus toys for my dog because he destroys stuffed toys almost immediately, and I liked that these were no stuffing. They ended up being a big hit right away. The squeakers kept him interested longer than most toys do, and he loves shaking the octopus legs around while playing. Since there’s no stuffing inside, I don’t have to worry about coming home to fluff all over the house, which has honestly been a huge plus. The toys are lightweight and easy for him to carry around, and they work well for toss and fetch too. I have a medium sized dog, but I could see these being fun for smaller or even larger dogs depending on how aggressive of a chewer they are. They seem decently durable for plush toys. Mine have held up better than expected considering how rough my dog can be with his toys. The stitching has stayed together pretty well so far. I also like that the pack comes with three because one is always getting hidden somewhere in the house. It’s nice having extras ready to go. These have definitely helped keep my dog entertained and busy, especially on days when we can’t spend as much time outside.

Durable Octopus Toys That Have Survived My Little Destroyer
Durable Octopus Toys That Have Survived My Little Destroyer These octopus dog toys have been a big hit with our Boston Terrier, who treats every toy like a personal mission to destroy it as quickly as possible. Surprisingly, these have held up really well so far. The toys arrived a little flattened and crinkled because they were packed into a fairly small box, but once opened they shaped up fine and still looked good. The material feels durable, and I like that there’s no stuffing inside to explode all over the house once the chewing begins. As expected, the squeakers only survived a few minutes, but honestly that’s normal in our house and not really a knock on the toy itself. The important part is the toys themselves have not been ripped apart yet, which is impressive for our aggressive little chewer. The colors are bright, the faces are funny, and the overall construction feels stronger than a lot of plush-style dog toys we’ve tried before. At the time of my review, these feel like a great value for a durable and entertaining 3-pack. Overall, a fun and surprisingly tough set of dog toys that have managed to survive longer than most in our house.
