    Great backpack

    I was nervous to see if my frenchie would like sitting in his new bag but he seems to enjoy it. It was a bit challenging at first to get him in the bag, and I still need help from another person to get him into it (the instructions video helps to some extent). My frenchie is 13kg (29lbs?) and the backpack is size L with a booster block. It fits him perfectly. I love the design and would recommend the backpack to others.

    Very nice backpack

    My dog ​​is completely relaxed behind me. A walk of more than 2 hours becomes a party for both of us.

    Worth Every Penny

    To some this bag might be a bit on the pricey side, but I am here to tell you why it's worth every penny.

    We love to go biking around the city, exploring new areas and new dog parks and this bag is perfect for long commutes, bumpy roads and jealous looks from passers-by.
    The comfy straps and waist belt makes our 30 pound dog feel light as a feather. The pouch underneath is great for storing towels, leashes, treats and more. It even has a special poop bag dispensing pouch. The best part is that it's also washable. Don't worry about getting it dirty, as our dog loves to roll in the mud. Just wipe with some mild soap and water and its good as new!
    Because we use it so often I am worried about long term wear a tear but so far so good!
    Overall, this bag has been wonderful and I easily give it 5-stars.
