Why for do you stick out your tongue at me?

My dad breeds labs and Jack Russells. I was outside playing with the
camera once again. So i decided to go up to the dog pins and take some
picks of the labs. Well I caught this one sticking it's tongue out at me.
HOW RUDE! ;)

This is my dad's house dog, Rusty.

This is my mom's housedog, Scooter.
