so she didn’t actually replace him with puppies bc that would be too obvious, she got younger dogs who were still old enough to pass as the previous dog and she had a habit of giving the dog makeovers (dying his grey hairs back to black , painting his nails etc bc “it’s good for his self esteem”) which made it less obvious when an older greying dog was replaced with a younger model. my uncle figures it out bc he moved back in with her to help take care of her and she couldn’t keep it from him when the dog switch happened
