    Bella loves her K9 sport sack and it fits her perfectly. She is 17 inches and 25 pounds, we purchased the medium. The pack is very comfortable and supportive. Love the water bottle and storage container. Highly reccomend.

    Our dog loves it!

    Our miniature schnauzer has never liked wearing anything other than her collar, so I was worried that she wouldn't like being strapped into a backpack.

    To help warm her up to it, we set it down on the floor, and put treats in random parts of the pack. We did that for about 24 hours before ever trying to get her inside it. When we finally did, she was a bit confused at first (after all, she thought it was just a treat dispenser!), but once I put it on and started rolling down the street on a bicycle with her, she absolutely loved it!

    She pretty much just sniffs at the air the whole time, much like when we drive in a car with the window down. She hardly ever squirms, so I think she feels comfortable. Now that she's had the bicycling experience, if I start to roll the bike without her, she cries with that "don't leave without me!" sound!

    Now that we've had the Knavigate for about a month, her disposition toward the pack is much like toward her harness - she still doesn't _love_ the process of putting it on, but she tolerates it because she knows she's going to love what's on the other side.

    Also, just gotta say - bicycling around town with a mini schnauzer on your back is adorable. People always want to talk with you about it!

    Lilo loves her Backpack

    It only took a few tries to get her used to getting in and out of her backpack. It has taken me longer to figure out how to put it on my back. Now as soon as she see it, she knows she is going for a ride. Lilo must be the most photographed doodle in our city. When you see her, post it on instagram! @lilojonesthedood

    Just wish i remembered to order her ID time

    We recently purchased our K9 Sport Sack for our tripod pittie a few weeks ago and we couldn't be happier. He was diagnosed with Bicipital Tenosynovitis last year and we have had to restrict his physical activity. We're an active family with two other dogs so being able to keep our little guy included has been very important to us. This purchase has made such a huge difference, and most importantly he loves it just as much as we do! We highly recommend this product!

    I love this pack! It connects to the dog’s collar to help me make sure my dog is safe and secure!
