Plot: This season, former adopters return to Villalobos in hopes of finding another dog to add to their family, Lizzy, Tania, and Mariah create a "retirement center" at one of the warehouses to give the senior dogs a special place to call home, and for the first time, the rescue team celebrates their favorite holiday, Halloween, with a special event to benefit the hundreds of dogs in their care. The rescues this season continue to make a lasting impact on the team, from an abandoned dog with a severe skin condition to strays that lead the Villalobos employees on a wild goose chase
