Works like a charm!
Color: Brown
Works like a charm. My puppy was crying and would not stop -as soon as I put batteries in and turned it on -my puppy went right to sleep and slept all night. I’d say that’s 5 stars.

I have boughtv3 of these! I bought one for each of my puppies. They still have them and sleep with them. My oldest dog is a rottweiler and is 4 now, she has kept her heartbeat puppy in almost perfect condition.

Worth the money!
Color: Brown
If your puppy has a hard time sleeping- just get it! Our puppy loves it and sleeps with it every night! I couldn’t believe the difference it made. He sleeps through most of the night now and only wakes up to potty!

Cute, unrealistically loud, and quickly outgrown
Color: Brown-D
This puppy is super cute. The heartbeat sound is louder than it needs to be. My puppy (8-11 weeks) doesn't seem to find it comforting. The cactus toys are cute but are destroyed easily. The rope toys in varying sizes are holding up well, but we will have to remove half of them as they are becoming a choking hazard size as our puppy grows. We've only had this a couple of weeks, and she's already outgrown most of what is in this set.
