    I’ve been using my Sport Pack 1 with my Golden Doodle mini for over a year now. Recently saw there was some ripping at a seem. I contacted customer service and they mailed me a new sport pack 2 at no cost! Wow great company!

    Game Changer for my Shy Frenchie! 10000% worth it!

    I bought the Sportsack plus 2 for our 30# 14 month Frenchie. Based off his measurements I ordered a Large and a booster block. He absolutely goes crazy when he sees me get the bag out!!! First time trying it around the house it took him about 5 minutes before he decided this was the way to travel. He is very anxious when we go out when he is on his harness in crowds and will completely freeze up. But! When he is in the sack he is ready to be social and go on adventure. He is super social when he feels secure in his backpack. We go shopping, to farmers markets, even a chicken sale! I have actually purchased another Plus 2 sack for our other full grown pups that would want to go out but tire out easily. We get compliments all the time on the SportSak and it is really comfortable to wear. I would love a waist clip on the bag if he was more of a wiggler but he rides great.

    We bought this for our 12 week old puppy (estimated his adult size using a towel to supplement the length difference for now) to help get him acclimated to it early on and give us the ability to socialize him with out worrying he could be exposed to something on a walk. He’s super in it and loves the views! Im extremely happy with our purchase.
