    Backpack comes in handy for training. My husband and I ate training to hike Mont Blanc in July. We have our pup walk 2-3 miles then pop him in the backpack. He loves it.

    One of the best earliest investments

    Was recommended by the vet to keep Kona away from dogs while we waited for her to complete her vaccinations. However, I still wanted to take her outside on hikes and this pack came in clutch on a trip to Arizona, allowing her to experience the outside world without worry of her picking up bugs. From hikes in the desert to walking around outlet/malls, Kona comfortably sat in her backpack. My only concern is that she may become too lazy knowing her owner is willing to carry her when tired 😅. So many people commented on the backpacks utility and wanted to get one for themselves.

    Hands down one of the best investments I made during Kona's first year of life. Will definitely be purchasing a bigger backpack for when I eventually take Kona on much longer hikes. Thanks for this amazing product!

    Great doggie back pack

    My son just loves the doggie back pack for his new puppy. Good dog also loves it!

    Great adventure companion tool for my frenchie

    The K9 Sports Sack Plus 2 in medium is perfect for my French Bulldog and I for our adventures. There is a bit of an acclimatization period to get her used to being in the sack, but she is now comfortable with it. This is a great product and it is really nice to have the customized patches easy to put into the bag to make it truly our own. Thanks for the great product.

    Best ride!

    Took our corgi, Rags, on a hike while on vacation. When the legs got tired, he was as happy as could be in his sport sack. Allowed us to continue further.
