My dogs fight over it
Color: Orange, Color: Orange
Easy to use, durable, and has a great battery love. At first my dogs were curious and unsure about it, now its become one of their favorite toys. They'll stare at it while its being charged and impatiently wait for it so they can have fun again. Perfect size for most breeds.

Haru LOVES this toy!
I recently purchased the Amazon Basics Hide and Seek Squeaky Dog Plush Toy, Rabbit and Carrot 5 Pack, and it has been an absolute hit with my dog Haru! This set has quickly become his favorite playtime activity, and it's easy to see why. From the moment I introduced Haru to the plush toys, he was hooked! The rabbit and carrot design is not only adorable but also adds an element of excitement and curiosity for him. The toys' quality is impressive, with sturdy stitching that has held up well to Haru's enthusiastic play style. The "hide and seek" aspect of the toys is brilliant. Each plush toy contains squeakers, which immediately captured Haru's attention. He thoroughly enjoys searching for the source of the squeaky sound and then triumphantly "catching" the rabbit or carrot. It's like a mini-game that keeps him mentally stimulated and entertained. One of the best things about this 5-pack set is the variety it offers. Haru never gets bored because he can alternate between the different plush toys, and each one presents a new challenge for him. Whether he's "hunting" the rabbit or "nibbling" on the carrot, his excitement is contagious! Furthermore, I appreciate how these toys keep Haru engaged for a good amount of time. As a busy dog owner, it's essential to have toys that can entertain him while I'm occupied with other tasks. The Hide and Seek Squeaky Dog Plush Toy accomplishes this perfectly, giving me some peace of mind knowing Haru is happily occupied.

Great toy
Great size for a medium to large dog and a good value overall. The carrot foliage is made of felt and can tear easily, but the carrot body and bunnies have typical toy durability. The bunnies include squeakers that are softer and not high-pitched. The holes are sized well—small enough that the bunnies don’t fall out on their own. Even with only a few stuffed inside, they stay put until your dog pulls them out.

I was shocked by how much my daughter's puppy enjoyed this toy!
I've bought two of these — one for my grand puppy to use when she's at my house, and another for her to keep at her house. I was shocked that she actually seems to enjoy playing with this toy! She hunts out all the bunnies and then brings the carrot to me to refill. I refill it, and then she takes the refilled carrot back to her spot and hunts them all out again. If I can't find one of the bunnies (because it's gotten stuck in the couch cushion, for example), I ask her "where's the bunny?" and she helps me find it! This dog is a ferocious chewer but she doesn't chew these toys! It's like she instinctively knows they are for hunting, not chewing. As a result, they have lasted a long time and provide hours of quality fun. Great value!
