If you have a scared new puppy, get this doll. I described my experience before and after the doll and notes for first and continuing use at the end...My 8 week old yorkie baby was having panicked screaming fits at night. I would have just let her cry it out but it was genuine panic for 30 minutes at a time and I don't want her to develop other anxieties later.Night before last, I ended up on the couch next to her all night soothing her back to sleep every thirty minutes until daybreak. It was exhausting.Over the course of that night, I did some research on training puppies to self-soothe at night and came across this product.THANKFULLY Amazon had same-day delivery so, within 6 hours I had it. It came with batteries and one heating pad so it was totally ready to go upon opening. I set it in her bed and petted her while she was next to it. It took about 15 minutes for her to warm up to it. She first laid on the edge of the bed, then face-to-face with it, then next to it, then across it. She took all of her naps with it yesterday. I kept the TV going and made sure I was talking in the room so she knew I was still there.Last night I ended up on the couch next to her again but she only needed soothing every three hours this time and her fits weren't TOTAL panic, just a little fear, so I'm convinced that it helped.The pictures are of her today for her first nap of the day. She still wanted to know I was nearby, but I petted her until she was calm enough to snuggle up by her "friend" and zonk out. She's happily napping as I write this review.NOTES:- The heating pad is supposed to only last 24 hours but, about 30 hours later there's still a little warmth in it.- I wasn't certain that the heating pad was supposed to go in the same pocket as the heartbeat machine but it was the only pocket on the doll, so I put them both in there, heartbeat first and heat closest to the surface and it didn't affect the heartbeat. 30 hours later, the heartbeat's still going strong.- The heat really stays in the belly of the doll, so I laid it on it's side to make it easier for her to snuggle close to the warmth.- The branded heating pad refills are a little pricey and I don't think the doll will have quite the same impact without the warmth, so I ordered the TonGas (spelling?) brand heating pads instead. They function the same, they're cheaper, you get 15 instead of like 8 and they advertise to last longer. So it's win-win-win-win lol. I'll update if they fall short.***update: the TonGas heating pads fell short. They only stayed warm for about 10 hours. It gets our puppy through the night but I wouldn't recommend them if you need them for 24+ hour periodsGood luck to you and your new fur-baby!
