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.

Great buy!! Would recommend

Color: Brown

Love this product. It is well made and worked so well to help our 9 week old puppy sleep at night. It is super soft and fluffy. It is as big as he is and he carries it around sometimes. He also plays with it and chews on it and it's holding up very well. He's 13 weeks old now. The heartbeat quality is good. I do not hear any sound, but you can feel the vibration in the dog. Not as realistic as I would have thought, but worked as we needed it to. The velcro that holds the heart in the product is very strong, it keeps the puppy out of it, me too sometimes. 😀 We looked at the more expensive products and this is definitely a great value. Well made and worth it. I would recommend this product! Truly a great buy!!

My 11 week old English bulldog puppy has found relief after leaving the farm with her siblings. Such a creative idea. It really works. Especially if you are crate training!
