K9 Sports Sack

I have been using K9 Sports sack for over 6 years. The latest version is clearly my favorite. I do wish the D Ring had not been removed. I have a dedicated collar that I use. The carabiner I find to be not comfortable for my Max.


This backpack has been a lifesaver! Our new puppy can’t walk long distances yet and we didn’t want to leave him home unattended for a long period of time, so we bought this backpack and it’s perfect! We chose the large size with the block to give him some height for now until he is big enough to not need it. He loves being outside and on walks with us. When we take out the bag, he runs over and sits in it, ready to go!
