Okay so my friends and I were randomly disusing the game, and I walked past the dog pen in town and saw some eyes in there (note: I'm in 24 of Summer), and then we started talking saying it would be really neat if you could adopt another doggo and make the two dogs have puppies!! So modders of the Stardew Valley region, I call upon you to create a puppy mod!! (If possible!) Thank you for reading!, -Astro
