We are having a slight problem with Max. He does do well during the day. He eats about 3;00pm,goes out around 6:00 and then while we're watching tv he comes and I love him and brush him till about 7:30 then Max is suppose to go to bed. This worked well until a couple of days ago..Now about 8:00 he starts whining like he has to go out. We take him out and he does nothing. This is not fun because it's getting real cold out. Any suggestions?
