Three weeks ago, I adopted a rescue named Princess. She is extremely fearful. Unfortunately, the shelter was unable to give her a shot for worms, fleas, and ticks and instructed me to give it to her around three weeks in. The problem is to give her the shot I would physically have to drive her out of hiding and capture her, which would undoubtedly make her very upset. Is it so important I give her this shot in a timely manner or would I be fine forgoing it? I don’t want to make her any more scared than she is.
