Duke & Lulu and Sparky - S2.E7

Karen's Dobermin mix is barred from dog parks for not only fighting, but instigating other dogs to fight. Emily's Pomeranian tends to bit off more than she can chew by picking on dogs twice her size. Plus, a therapeutic terrier helps AJ control anxiety, but tends to attack other dogs on walks. Can Cesar help these owners get a handle on their overly aggressive pooches?
