Two weeks ago, Sydney went home.
I packed her tiny suitcase with some food and treats, a favorite toy (really her second-favorite, as the #1 toy was too disgusting to leave the house), her medical records, and a copy of Patricia McConnell's booklet Love Has No Age Limit.
Then I took her on one last tour of South Philly to say farewell to the city and make sure she was thoroughly exercised before her seven-hour car ride to upstate New York.
And then she met her new people, and did the happy foster dog snuggle thing, and never looked back. The last I saw of Sydney, she was trotting off happily between her new people, tail wagging in a joyous blur.
Her adopters have been keeping me updated on her progress. She settled in well, promptly made friends with all three resident dogs, and has daily adventures investigating the woods around her new home. She's a happy dog and they're a happy family, and so the story ends well.
