My cats are too lazy for this
Color: Pink
I bought this in hopes that my cats would find it entertaining, as they've never had to work for treats before, they unanimously decided to simply meow and look cute. THATS all it takes and poof! They get a treat.. (It gets me every time). It is an interesting well made item and seems sturdy and intriguing, my cats are just spoiled Lil stinkers who don't want to "struggle" to get a treat...lol

Perfect puppy starter kit and gift! Perfect for plane rides and kennel!
Color: Neutral, Color: Neutral
Perfect puppy gift! We use the kennel as her safe haven, and for potty training . This heartbeat tool is amazing and helped our puppy get acclimated to her kennel. She goes into her kennel and sleeps with it on her own. It calmed her down on the plane completely. We had a 6-hour flight and she did fine with the heartbeat toy. At home innthe kennel, the whining was very very minimal the first couple days, then it stopped. As you would hear and see her snuggle up and fall asleep. I think it is a bit pricy, but not too bad for the benefit. The heartbeat is seperate and is putninside a pouch on the stuffed animal. The blanket is soft, beautiful and perfect size. Good quality fabric. Both chew toys were loved by her.I do notice my large breed puppy prefers the rope and small tennis ball type chew toys. However, she plays with these too. Haven't used the heating packs yet, they go inside the pouch with the heartbeat item. I am sure we will because my puppy does love to be in front of my small heater under my desk to keep my feet warm. The packaging was extremely nice and fancy and was complimentary to the items inside.

Best Idea for Puppy's First Day Home
Color: Pink
I was a bit reserved on purchasing this kit because it was a bit expensive. After a month now with my pup at home, this was the best investment for us and our GSD. On the first night, we used the heart beating snuggle puppy and blanket. She slept the entire night without an accident or a cry. The heartbeat in the snuggle puppy and the heat pad was the best idea. Our puppy never felt alone (just fyi, her crate was in the room with us for the 2 weeks). A month later, she is so protective of her snuggle puppy. We only used 1 heat pack to soothe her during the first week. The heat packs last a while. Our GSD now uses the snuggle puppy as a pillow or an object to be close to while she is in her crate. Any new puppy owner could definitely benefit from using this. Of course, with all things puppy, it does require a bit of time to correlate toys as a positive thing. We exclusively keep the snuggle puppy in her crate and make it a part of her secure place. My GSD puppy did really care for the teething heart toy. Even after freezing it, she didn't care for it. She also outgrew the small toy. She will chew it from time to time but it doesn't entertain her much. I found the kit, overall, very helpful with our puppy's adjustment to our home. She sleeps through the night since 8 weeks old and now at 12 weeks old. We've never had an accident in her crate overnight with the help with the snuggle puppy.

Amazing kit for your puppy
Color: Blue
We’ve had 6 puppies over the years, and this is the first time we’ve had this wonderful little kit to welcome our little one home. We had the blanket with his litter so it smelled like them when he came home. He he loves that blanket, he loves the dog with the little heartbeat, and the teething toys. The 5 star review is because everything in this kit is so well made, really wonderful quality, and a great value. The blanket is a very nice thick plush, not some cheap one. The stuffed dog is big and fluffy and well made, the heartbeat works wonderfully, and the little chew toys safe and well made.i would encourage anyone who’s bringing home. A little one please get this first. It’s going to make your pup more comfortable when they get home, and will help then sleep better during the night and their naps. Very Well Done !

A must have for a new puppy.
Color: Pink
I just got my first new puppy in many years, and I was searching for ideas of what items I should get to be ready for her. A dog forum I belong to gave suggestions for items to prepare for a new pup. One of the items listed was a snuggle puppy. I was not familiar with the product, and did some research. I had always heard that lonesome puppies respond well to a hot water bottle and ticking clock for comfort. A friend had suggested a stuffed animal. I found all of that in one package - The Snuggle Puppy! And even better was the complete new puppy package. The blanket is adorable, very soft and the perfect size. The toys are perfect, and they include extra warmers for the puppy. I keep my girl in a kennel at night with her blanket and puppy. The first night I tried just the blanket, and she cried and howled for 15 minutes. Then I turned the heart beat on and put the puppy in the crate with her. Within 5 minutes she was quiet and stayed that way all night. I have used it every night since and not a peep. (It's been a week now). I would highly recommend these products to anyone bringing a pup home - it was a sleep saver for sure and she seems to love it.
