Hurricane (1 and 1/2 yrs.) used to sleep soundly through the night in bed with me and my husband. Just recently he has started waking up several times during the night to be let out. Sometimes he goes potty and sometimes he just barks. We haven't changed our sleeping pattern - we all still go to bed at the same time as usual. It is starting to be a bit of a pain considering we haven't had a full night sleep in a few weeks. Hurricane is not eating before bed and we let him out before we go to sleep too. I was just wondering what could cause this change in his sleep pattern.
