Dog Show Cart- Mighty Mite Dog Gear Dog Show Cart. Could definetly use this at flyball to tote the boxes, balls, metal crates, xpens. Love the tall handle so it doesn't ram the back of your legs going downhill.
The Variocage is not for every pet owner, although I wish it were. It seems to be one of the safest car crates around, especially for medium to large to very large dogs. But you really need to dedicate your cargo compartment to the Variocage
