Sadly I got this for my new german shepherd pup and she has all but grown out of it within a week! I would recommend this for a smaller dog though as I have ragged it around the forest every day - half expecting the wheels to come off, but they didn't! I was impressed with the sturdiness. Though my pup will have outgrown it very soon, it will still be handy for the cats if they ever need to go to the vets so it wont go to waste. One caviat - i wouldnt recommend if you are tall - I am 5 foot 8 and the handle is a little low for me, also the back bar on the back wheels interferes with my natural stride length. Am guessing if you are under 5'6\" it'd be fine, but for us lanky people, it's a bit faff to get used to!
