Hi there
Dogs are probably just as confused about this situation as we are, if not more. They’re not used to having us humans home all day, and all of a sudden, we’re there 24/7, watching them, playing with them and giving them more attention than ever before. They don’t know what’s going on, but they must sense that something isn’t as it used to be.
Pets need their routine as well; once they get used to something, any change might be very unsettling for them, and let’s not forget that now that people are home all day with nothing to do, they probably shower their pets with attention. That’s why this dog is spending most of his time looking out the window, as if he’s sensing that the streets are empty, wondering away.
