dogs have different amounts of time in their years then us humans ( 1 dog year = 7 dog years ) so its like every minute for us is like days for them. so does this mean that everything is very very slowed down for them? if so, they must have slowed down hearing.. so what if a bark is like just plain english just very very slowed down, so it sounds like a bark to us, but its actually a full conversation for them. like if your neighbors dog is barking at you, it sounds like annoying barks, but really hes trying to have a conversation with you.
