Sometimes
I have one chihuahua who is an inside dog. He goes potty on the deck in the morning and doesnt have free inside/outside reign on his own. So of course he will not be outside without us. He generally only follows me around the house (lol) and does not wander around to look out of windows and doesnt bark at anything typically. It is a possibility, but very unlikely. Your dog would have to approach windows that are far from the play area to be able to possibly see him.
See above, about farm dogs. Has only happened once to us, and the farmer had told us they escaped.
