    Good security and comfort

    My Irish Terrier enjoys being high up on my shoulders, great bag, bought only for use on crowded public transport or cycling, now just need to buy electric bike as he's a little too heavy to push up hills!

    Awesome Bag

    Stan gets to go on all his hikes again after being diagnosed with a spinal condition. He is just as engaged and can now see everything! We still need a little more practice getting him in but he loves being in it. On top of it all, incredible customer service. So friendly and helpful after we ordered a size too large.

    Great bag

    We have 2 bags from this company, and this one takes the cake. The structured back and extra straps really, really help carry some of the weight of the dog and allow for longer time out and longer times without needing breaks. The extra storage space on the small size allows for my hoodie, his hoodie, my camera, a pair of ice cleats, and my wallet. With the big bag we probably won't use the little one for much more than errands around town, but it's nice to have both


    Cool. People loves it =)


    I love this for my 14 year old beagle. She loves being outside and going on long walks, but her body just doesn't have the stamina anymore. We have a golden retriever puppy but I couldn't stand leaving the beagle at home anymore. Enter the Knavigate. I wear it on my back until my beagle gets tired and then put her in it. There's no stopping us from taking her on adventures any longer. So worth it!
