If I seen a bear with my dog, he'd bark at it, then hide behind me as if to say, "I got it's attention, now he's all yours!"
He's a Shih-poo, and he's learned to bark at almost anything that moves... thanks to being at my mother's house while I'm at work. He loves to bark at the squirrels, birds, cats, bikers, etc. that go by the window.
Last time I had him out for a little hike, he was pretty well behaved. I'm curious to see if he'll bark like mad with just me around, or if it's a house only thing with him.
Might take him for a short over-nighter in the tent this weekend.
