SmartPetLove Replacement Heat Packs for Snuggle Puppy. 12 Replacement Odourless, Long Lasting Disposable Hand Warmers Made with All Natural Ingredients.

I got these to use when the ones that came with our Buddy Dog ran out. From reading another review somewhere I learned I could get 2 or 3 nights yse from each one by sealing it in a small Ziploc bag when not in use. It heats when air hits it, does not heat when sealed. After a few months we no longer needed to "heat" Buddy but these are a great product!

Just open the pack and shake vigorously for 20 seconds and it heats up. These made our pups anxiety plush toy/friend nice and cozy.

We brought our puppy home and used momma dog (that’s what we called her) the first night. It worked so well we got on here and ordered two more packs of these. Between the stuffed animal and these heat packs it’s a little pricey but it’s 100% worth it. We even tested one night so we could be sure it was actually the heartbeat and heat packs and sure enough, as soon as we put it in kennel he quieted down and went to sleep.We got two packs and had maybe 4 or 5 of these left that we didn’t use. By then he was going to sleep and we’d forget to use momma dog.

Perfect for my puppy’s stuffie

I would recommend these very strong way. If you have the product they’re supposed to be used in otherwise they’re very expensive although they really do hold the heat for quite a while.

I use them to help keep feral cats warm outside!

I used these in my outside cat houses during very cold nights.

This is amazing! The first pack lasted 30 hours. We have a kitten that was abandoned by it's mom at 10 days old and we can't use heating pads cause we don't have power 24/7. These heating pads work amazing.They have literally have saved this kitten's life.
