The first episode features terrier-cross pup Teddy who is tormenting his feline housemates Ernie and Molly.

Chirag and Nanci break up the fights between a cat and a puppy belonging to a Devon couple, and try to control a dog in the Peak District that chases everything.

Nanci and Chirag face their biggest challenge yet with two households where there is real fear that recently arrived big dogs could injure the resident cats.
