There were a few different inspirations.
- First, I always thought Bobby’s pup Rumsfeld should have survived for longer than five seconds. We get to see the pup stretched out on one of the cars in the junkyard during Season 1 Episode 22. We never see if he died or not when Meg arrived, but considering he’s never seen again, most likely after the yelp she killed him.
No Meg, no dead dog. ;w;
- Second, Sam needs a dog. No matter what world we’re in, canon or AU, Sammy needs a pup. Hence the beginning of a beautiful relationship.

- Third, once the ideas for the pup started coming, they didn’t stop. It was meant to be.
