Just got this to use on an upcoming trip. Looks really well made. I’ve been wearing it around the house a bit and Reed jumped right in. He seemed really comfortable and safe.
My Wholesome Pet –
Enjoy your upcoming adventure.

We love this bag! Perfect for our toy poodle who would get tired on long walks and just lay down waiting for us to pick her up and carry her. We bring this bag along with us now for when she gets tired and she loves it! At first she wasn’t cooperative in putting her in the bag, but after a few tries it went smoothly. Also, great customer service!!
My Wholesome Pet –
We’re so glad you’re happy with your purchase.

Amazing Product — Even Better Customer Service- This backpack is very well made and has a million and one pockets for storing all kinds of stuff from bags to little treats. We love the way you can adjust the straps and the buckles to really cinch the passenger within. Our pup is a bit skittish but she loves the backpack and will readily come to be put into the pack. My one caveat is that putting the pup inside the backpack can be challenging. Practice makes perfect — so don’t give up it does get easier.
My Wholesome Pet –
We’re so glad you’re enjoying your new pack.

This is the 2nd one we have purchased. We love it so much for our fur baby that we purchased a 2nd one for our vacation home.
Molly loves to go everywhere with us. Probably the best item we have purchased for her.
My Wholesome Pet –
May you and Molly share many more adventures together!

We did some pre training with our dogs to get them used to climbing into and being zipped in a backpack (using an old hiking pack) before ordering these. So far, we are very happy with the packs! It is very easy to get each of our dogs into the pack and the fit is excellent. One is short and stout and the other is lanky. We are looking forward to biking into town with them on our backs.
My Wholesome Pet –
That’s great to hear! Thanks for sharing.

We are so excited that our little lady with arthritis can keep joining us on our walks and hikes- she doesn’t have to miss out anymore!
My Wholesome Pet –
This makes us very happy!
