How did Pip feel about Edi when she first joined your family? Do you think she'll react differently with Second Puppy?
Pip thought Edi was gross and horrible the first few times they met (~1 day old, ~6 weeks, ~10 weeks). But when Edi came to stay for real, she warmed up within about 2 days, much to my surprise and happiness. It took her a few days to figure out how to play in a way that wasn't scary for baby puppy, but they LOVED each other. Edi was obsessed with big sister, and Pip was a great babysitter.
Once Edi was around 6 months old though, baby privileges ended and Pip lost interest. She doesn't like Big, Strong Edi who bumps her in the head while running high speed. Pip mostly ignores her now, and will only play if she is third-wheeling another dog and Edi, never playing with Edi herself anymore lol. Edi is mostly respectful of her, but still tries to be annoying sometimes. She can't help it; the ants compel her.
Pip enjoyed meeting a friend's new puppy last week, but I have no plans to inflict another baby on her for real any time soon lol.
