Gertrude first appeared in "Olaf in Love." She came to Shelter 17 looking for a puppy to adopt. She met Olaf, mistaking him for Mr. McLeish. The two were attracted to each other, but didn't act on those feelings. Gertrude soon left, having adopted Kiki.
Gertrude returned the next day, saying that Kiki was not at all happy with her. At Kiki's urging, the Pound Puppies secretly pushed Olaf into asking Gertrude out via a phony radio show. Unfortunately, their over-the-airways prompting made Olaf seem like a jerk, and Gertrude stormed out, intending to accept a job offer several miles away in Springdale. When Olaf came to convince her otherwise, she was revealed to have stayed. She and Olaf reunited, kissed, and embraced Kiki together.
