The second part, not actually! If the love interest isn't a good person or at least a person who does mistakes, it is a thing that happens IRL unfortunately since they don't realize the kind of responsibility they're just giving out.
A bookstore about dog breeds is a little far fetched though, bookstores are already not doing well in recent years so a niche one feels odd. Maybe a pet acessory store that has books, or the bookstore is normal but the pet/dog section is her favorite? Of course, this is if you want a real-sounding, modern day place; a fantasy world or a place that takes some liberties can get away with it fine.
