That reminds me. A lady in the neighborhood used to have 3 Belgian Sheepdogs. She told me that they started with 2 puppies and when they grew up and had puppies of their own, she couldn't believe it. She (Honestly) didn't know she had bought siblings, girl puppy and boy puppy .

How is it possible with the two pups she never noticed once - one was a boy and one was a girl? I'm sure she didn't know about the pup she kept from the litter. I mean dogs aren't chickens. You know at birth what you have. Scary
