Works well. Cuddly.
Color: Black
Worked well for my Puppy. Ended up taking out the heart beat and she was fine. She still cuddles with it in her crate at night. Holds up well to puppy teeth.

Great BUY!
Color: Yelow, Color: Yelow
Great product! I bought this for our puppy we were getting since she was going to now be away from momma. As soon as I turned the heartbeat function on she started to lick the toy and laid her head on it. Needless to say that we slept throughout the night because of this toy. She loves it! The heartbeat function is pretty noticeable too!

The best for crate training
Color: White
Crate trained our new puppy the 1st night I put this in his crate! I highly recommend! Great quality! The back is just a little hard to open to turn the heartbeat on and off.

Perfect for my pup
Color: White, Color: White
At first I thought this was going to have a cheap quality and an uncomfortable fur like material but I was soo wrong. This stuffed animal is light weight but the first night my 9 week old bernedoodle slept with it, he fell asleep so quick and it was the first time he didn’t cry in the time we have had him. He loves to cuddle with this stuffy during nap time and when the heartbeat is on, he doesn’t chew it which is crazy because he loves chewing on stuffed animals. If you are even considering getting this, I 100% recommend pulling the trigger. Love love love it and it is a new necessity in our house

Nice quality , works well
Color: White
Washable, does exactly what it says . Place the plastic heart inside and it works. If you want to turn it off , locate the button while it’s still inside and press and it turns it off
