If I am honest, Biggie's biggest flaw is that he is not Mack. His second biggest flaw is that he is a Golden Retriever.
Goldens are the most popular dog in the US (maybe not an actual fact, but seems likely). People love them with a cult-like fervor, will cross the street to pet one. I know people that only have Goldens—one dies and they get another. Yet, when I complain about Biggie's behavior they're like, yeah, all Goldens do that. WTF. Why didn't anyone tell me this??
