The cart was bought new .. I had a 70 lb lab that used it for 2 months .. And about 4 x a week for àn hour .. It is assembled in the 4 wheel position .. It is adjustable .. But it is at the smallest position right now .. You can text me at 413 3885941 and I can send u a pic .. I did pay $ 600 for it...
