Imagine your surprise if you picked up a dog from the kennel, only to find it's not your dog at all! When I first read about this unlikely story, I instantly dismissed it. I know North (and his crazy antics) and can't see how I could ever bring home a different dog and not realize it.
Well, in this story, neither black lab was picked up by her actual "parents" — LaiLa (seen here) was retrieved by the owner's niece and Bella by the owner's parents. When eventually reunited, they suspected something was wrong but assumed it was just an angry response to their prolonged absences. After a microchip scan, the real identities came out and the rightful swap happened.
