    Our cattle dog x kelpie adores this backpack. She’s deaf and we weren’t sure if it would be sensory overload, nope! From the second we got her in we haven’t looked back. We take her on long fast bike rides and she sits tall and loves life! We get so many smiles and laughs as we pass people, it brightens everyone’s day. Couldn’t recommend this pack more! We also got one of the water saucers and it’s fantastic! She loves drinking out of it and it’s nice that she has her own bowl now on hikes!

    Great So far

    My dog doesn't hate it and gets more used to it every day. I think its amazing.

    Expected a Lot, Got More Than I Expected

    Reggie loves it. He is calm, observes everything, and keeps his paws on my shoulders. Of course, his barks go right into my ears. Oh well.

    The padded shoulder straps are excellent. The strap connecting the shoulder straps choked me until I learned they slide up and down. A hip strap was the best improvement when K9 introduced the Knavigate.

    Well done and worth the price.

    Excellent !

    A perfect design, high quality product that MAX and I love ! I will relocate to France this summer and can tell you that your product will be very successful there !!!
