I just got two greyhounds, and im wondering if when they stay home alone, will they really just sleep?? Or will they do some things to make trouble(like chewing up furniture, barking, peeing??).
Also, i've heard that you can't trust a greyhound off leash. Does this rule still apply even if you train a dog? For ex. my old shih tzu,(rest in peace

) would never just run away into the street or somewhere else. THANKS!!!!!!
