Got this to help the new 9 week old puppy with adjusting to being in a new home. Put it in the crate with him and drove the two hours from the breeder to home. The pup never cried in the crate! Even at night when we weren’t near him. It may be that we were fortunate to get that rare pup but, I’m pretty sure it was the Soothebuddy. We only turned on the heartbeat device at night. Definitely recommend. Especially for the price is worth the try.
