So much fun!- Izzy is very much enjoying her new K9 sack. The videos on how to get her into it and how to adjust it for comfort were very helpful. Izzy quickly learned that the bag means GO time and gets excited as soon as I pull it out. We have been walking and for bike rides with it so far. We will be trying it out on the motorcycle once it’s warm enough to ride.
I highly recommend this bag.
My Wholesome Pet –
So glad you and Izzy get to spend more time together!

We LOVE our pack!- My frenchie gets tired on the second mile of our daily walk. Frenchies also cannot regulate their temperature due to their Brachycephalic heads. The pack has come in so handy for our daily walks. We get lots of comments and people really get a laugh from seeing her in there.
My Wholesome Pet –
May you both enjoy many more adventures together.

He’s going with me everywhere!- I think it’s safe to say, we both love it! I took him on a long hike and although we got a little warm, it was pretty comfortable.I plan on taking him on hiking/camping trips so, I would like to see a bag that has more storage for myself underneath the dog compartment. Also, a waist belt would help take some strain off of the shoulders! Overall, I’m very happy and I think I made the correct decision after shopping around!

We’re so glad to hear you’re happy with your purchase.

I did a lot of research before this purchase. This carrier is a homerun. It’s comfortable to carry with its well padded back panel and adjustable straps and best of all Pepper seems really happy in it. Great carrier. Very happy with it.

The bag is super comfortable for not only me, but also my dog. He is very comfortable sitting and being in the bag for long periods of time and he absolutely loves it.
