Front extension carts are used on pets that are starting to weaken in the front limbs and need a little extra support. The wheels are spring tensioned castors that rotate and flex as the pet moves over both smooth or uneven surfaces. The extensions can be attached and removed from the cart in seconds with no tools required. This allows your pet the option of the extra support or not depending on they are feeling on a given day. The front extension cart is a standard cart with a clip on addition. This is very handy, because if the pet gradually weakens over time the front wheels can be attached whenever needed.
