We love this backpack; excellent quality. Getting puppy in requires some practice but he enjoys it so much so now gets excited to get in. We get so many reactions and smiles from people around!!! And my 4 month old absolutely loves going for bicycle rides or just being in it overall; helps with taking him to places where normally dogs aren’t allowed, like grocery stores.

Fits my pet and he is secure while taking a bike ride. Pup is a chewer , this pack is very durable and stood up to his choppers. Would like it to be a little more stable when trying to put pack on back and taking it off. Have to get lower to a table , counter or something for pet to be stable especially if it fidgets in the process of loading and unloading. My pup feels secure once in and rests paws on my shoulders while putting head in air. It’s nice that I can see him over the shoulder . I thought it would be difficult to get pup in. Once I figured out the process it is not any harder than a harness just as long as pet is calm. There are detailed directions with pictures but they were on cards attached to pack. When I detached it, they fell apart and out of order, hence my need to figure it out.

I already own a K9 dog pack that I have been using for many years so our late rescue could enjoy morning bike rides and biking adventures. When she passed I was tempted to donate the back pack but decided to hold onto it. I am glad I did because we will hopefully be adopting a new rescue that is not ad big as our last fur kiddo and thought she would not fit properly in the back pack. I was so pleased to see this item available from the K9 line of products. It fits in the bottom of the back pack PERFECTLY... I will make a removable cover for it so I can launder it. So please that IF our new fur kiddo chooses us to adopt her she too will be able to ride along with me... Good product, good firmness, and perfect thickness to boost her little butt! Was nit expensive and way less expensive than buying a new back pack!

$35 duty into Canada. Haven't used it yet, still desensitizing dogs to it. Looks like great quality. I have 26 & 31 lb Boston Terriers. This is for emergency while on hike & when older one is completely blind & might need to sometimes be packed around. Got1 booster block, need another for little guy but glad I went with medium not small.
