Episode 3 (S01E03)

In Sheffield, Graeme Hall steps in to assist the owners of Bella, a collie whose aggressive behavior has escalated to the point where no one can visit their home, and the family is unable to take her outside. He also encounters Toby, a feisty basset hound who loves lounging on the kitchen counter, and Dave, a French bulldog with a troublesome habit of snacking on his own waste.
