      Great bag, I bought it for fourwheeling. (ATV)
      And it is a success. I use it for a Boston terrier 20 lbs.

      Great pack!

      This is a well made, well designed pack for our little shorty Jack Russell. The sizing was perfect, following the sizing guidelines provided. We followed the training guidelines and were amazed at how quickly he adapted to being in the pack. He actually seems to like being in the pack and looks quite comfortable in it. He gets tired on longer walks because of his short little legs, so this is perfect for him. Now we can take him on longer hikes. Love the fact that there is the extra pack that can be attached for taking his water and gear. Great product! We received the pack in under a week after ordering.

      Sack worked well once we got the dog into it. Dog was comfortable in the sack once he settled down and got used to it.
      The sack is well designed and very sturdy.
      As seniors we found that in our case we could only carry our 19 lb. dog in the
      sack on our back for a maximum of 30 mins.

      Fantastic product!

      My 9kg Cavapoo is super happy and relaxed hanging out in this bag when he’s had enough walking, or if we go for a bike ride. A few times he’s even started to drift off to sleep. He knows now that he will get a carry when he’s tired, so he almost jumps in the bag himself (it took a bit of time and patience to get to that stage). It would be even better with a hip strap to help distribute the extra weight. Unfortunately the only K9 bags with a hip strap are designed for very tall people. If this changes I’ll be buying one. That said, when he’s gotten too heavy for me after a while, I switch the bag around and carry him on the front.
