    For our tri-pawd

    This bag works really well for being able to take our three-legged dog on longer walks or out on hotter days. Took a couple times for him to get used to it and for us to find the right level adjustment to keep his weight centered. Because of the weight of our dog (35 lbs), it's much easier to use with a partner to lift the dog onto the other person's back and adjust when he's in place.

    The life of the party.

    The pack arrived in good time. Quality is excellent. This pack has rescued us many times. From a walk going to long, and needed to give Ein a break. Went to a Canada Day event where there were so many people we had to pick him up to keep him safe. Going into stores instead of one of us having to stay in the vehicle. Every time he is in the pack, people are constantly looking, pointing and making comments about how cute Ein is and how happy he looks in the pack. This has been one of our best purchases EVER for our furry family member.

    Amazing sport sack

    This was a Father’s Day gift to my husband who is a dog dad we adopted Maggie when she was 11 years old and cannot walk not stand. she is now 12 and we were so hopeful this would allow her to travel with us more comfortably. But unfortunately with no fault of the bag she was not comfortable and got hot even on a cool breezy night. Because of her age it’s harder for her to regulate temps. Still love the bag and how well it was made just won’t be used because of our pups needs.

    Well made

    I was pleasantly surprised by the quality of this product. It took a few training sessions to get my dog used to getting in but once he realized he enjoyed the ride, it became much easier. My one issue with the pack is that because there is no waist strap, the entire weight of your dog is pulling on your shoulders and neck. I can only carry his 30 lbs about 30 minutes at a time. It is not a flaw in the design, just that the pack isn't long enough to have a waist strap. I guess it's something to think about if you want to carry a medium sized dog for any length of time. I would recommend this product for someone with a small dog.
