The Thompson pack is recovering from past trauma at the hands of an abusive ex-husband. Now, the women have suffered another tragedy: coonhound Nyla has become explosively aggressive, accidentally killing one family dog and viciously attacking another. Cesar needs to help the entire Thompson pack heal from past wounds and rehabilitate Nyla before the family is faced with a heartbreaking decision.

Cesar works with a Mexican breed close to his heart when he rehabilitates twin dogs whose over-excited behavior has put their owner at risk of eviction from her apartment building. Later, an actress turns to Cesar for help with an overprotective pint-sized pooch that's creating too much drama of her own.
