The pressure is on Joe to succeed at his first Mother's Day. He wants to pamper Terra, but that isn't his only challenge. Penny requires 24-hour care and an exhausted Terra begs Joe to watch Penny all by himself for the afternoon. Will this Mother's Day be one to remember, or one that sends Joe to the doghouse?

Joe's family visits and Terra storms off from a family dinner when the conversation escalates into a heated debate about religion and how they plan to raise Penny. Tension remains between Terra and Joe during their first family photo shoot and tears are shed when Joe and his mom have a heart-to-heart about Joe's deceased father.

Terra and Joe are startled by some troubling news about their neighborhood and decide it's time to amp up home security. Terra rallies for the dogs to return home and Joe purchases a weapon without consulting Terra. Meanwhile, Terra and Joe struggle with a difficult medical decision as Penny's vaccination appointment nears.
