MINNEAPOLIS (WCCO) -– The Dog Agility National competition takes place all this weekend at the Washington County Fairgrounds in Lake Elmo, Minn.

One can see dogs of all sizes compete, weaving in and out of poles, riding seesaws and leaping over beams as they speed through obstacle courses.

Nearly 500 dogs from 29 states have entered into the competition.
