Alice's Mysterious Mystery

A mouse and his boss pose as dogcatchers and grab a schoolhouse full of dogs; they use several other ruses to round up dogs for, as we discover, a sausage factory. Alice and Julius are on the trail soon after the first caper, but it takes them a while to catch up with the bad guys. They do, and Julius tricks the big boss into getting clobbered by the sausage guy, then turns the dogs loose on him. (imdb)
