Unlocked the ability to bring our aging dog now!

The K9 pack has literally helped us immensely with now being able to bring our 13 yr old Chihuahua on our walks or hikes where as previously, we were locked with either carrying her in our arms OR just not bringing her all together. This has been a game changer to allow her to see and smell/sniff and enjoy the fresh air as much as our other dog on her 4 legs! Thanks for making such a animal-forward item -- it's helped our family in more ways than I can express!

We gave our daughter one for her dog and she loved it so we had to have one for our Pippa. ❤️❤️

Love It!!

Today is the first day that I was able to use it. We did a short hike and Penny did great. I picked up a small and I think she needs a booster, which I went ahead and ordered. I am looking forward to taking her with me more. I highly recommend it.

Great for travel

Our corgi was happy & content while in the backpack. He got a lot of pets from people & he loved every minute of attention he got. Although, I would have liked for the backpack to have some form of neck support for when he falls asleep. Overall great purchase!
