The bag is very pretty. However, the front zipper, which is the pocket where my front door key is, is a bit stuck on my bag. Stupid when you have to fumble around outside the front door. I also weigh 64 kg at 1.76 m and the bag slips on the tightest setting. It just about holds, but I couldn`t run with it. Of course, that`s pretty impractical. If the dog runs away, you have to decide what is more important to you: dog or valuables...
