Excellent Bag!

Start slow-just giving your dog treats when s/he smells the bag, then putting in the front feet and rewarding, zipping up the bag then release—and after a few weeks of working your way up, your dog will be so excited to jump on your bag and GO!

Mia is a 65lb AmStaff with elbow dysplasia. Her elbow prevents her from accompanying me on longer runs/hikes. 65#s is a lot to have on your back, but I love cycling around the San Francisco Bay Area with her on my back. With the bag, she is allowed on public transit, which means that we can visit her mom in the city without having to drive! It took a while to acclimatize her to the bag, and is difficult to do by yourself, but not impossible. With another person who can lift the dog, it is quite easy!

The thick shoulder straps distribute weight well, and the strong waist belt helps transfer some of the weight directly into your pelvis. The integrated poop bag holder on the waist belt is a fun addition too. I have yet to use the attachable storage bag, nor the removable hood, but am glad for the option. The only thing it needs now is an anti-gravity spell!

When I first ordered the bag, I ordered too small for the length of my dog, but the customer service picked up the phone on the first ring and expertly helped instruct me on the return path (which was complimentary).

Overall, I am extremely satisfied with this bag. With hindsight, I would still have bought this!

I tried a couple different styles of packs to carry my Shichon dog Louie with me on my motorcycle. I never felt really comfortable till I found your site. He loves it! He gets all excited when he sees me grabbing it and makes it easy for me to get him in it. We travel all over the place. The pockets are perfect for a bag of biscuits, a collapsible water bowl, a leash and the waste bags. My husband and I go on some longer rides, so we stop, let him stretch his legs, relieve himself and he is ready to hit the road again. Your packs are extremely well made and I really like that the straps securely hold him in. He got a biscuit at a drivethru and I made his picture into a meme. Thank you for making a product that allows me to bring my adorable side kick with me safely.

Best backpack ever

I'm in love with this

We have a three legged border collie who loves to hike but she is limited in range, 2 miles max. The Rover 2 is a fabulous find that now allows us to include her in longer hikes. We were so excited to find this pack. It’s sturdy, comfortable and best of all, allows us to include Lucy in all our outings.
Customer service was great when we had to exchange the large for an extra large. Fast and easy. I highly recommend this product.
