My puppy (4 months) is growing up so fast! He's started to venture out, discover new things.
I have a fairly large big screen in my bedroom, and he's never paid any attention to it. You can see its reflection in my dresser mirror. Last night he saw the reflection, not the TV itself, and barked and carried on. This AM he was standing on the bed, looking at his own reflection, and growling.
I don't think I've ever had a dog notice himself in a mirror before.
Is this common?
