It took a few tries to get the hang of the backpack and to get the right size. Now we are building up time walking with Crystal in the new pack. 18 lbs is a lot in a backpack! I am looking forward to building strength, endurance and most importantly - more time with my 10yo Shih Tzu pup. So glad we found a fit!

My Spoo can go anywhere with us right now till she gets fully vaccinated. Then we will have it when she is tired and can't walk anymore!!! Fits perfectly

This is my 3rd Boston Terrier and always had another brand backpack for them. Problem was they didn’t sit well in it as they were positioned sideways. Randomly I found K9 Sportsack and I’m so happy! I got the trainer for the new puppy and will upgrade after a year when she’s full grown. I have the bolster block in there and had no trouble getting her in. I have larger dogs that I take for 3 mile walks every morning and little 9 week old pup couldn’t hang—she walks about a half mile and wants to get in her bag. The only thing is chest straps should be standard on all models, besides that, zero complaints and all praise.

K9 Sport Sack is great for both me and my young friend Chance. Very comfortable and cool for both of us.

I saw it on Instagram and I falled in love of the idea to go outside with my dog, is a mini bullterrier and its perfect for him. I also purchased the snuggler for cold and windy days. The backpack is very confy and confortable.
