BATHROOMS:

Always accompany guests to the bathroom. It is not necessary to do anything. Just sit and stare.
DOORS:

Do not allow any closed doors in any room. To get door open, stand on hind legs and hammer with forepaws. Once door is opened, it is not necessary to use it. After you have ordered an "outside" door opened, stand halfway in and out and think about several things. This is particularly important during very cold weather, rain, snow, or mosquito season.
CHAIRS AND RUGS:

If you have to throw up, get to a chair or bed quickly. If you cannot manage in time, get to an Oriental rug. If there is no Oriental rug, any quality carpeting is good. When throwing up on the carpet, make sure you back up so it is as long as a human's bare foot.
HAMPERING:

If one of your humans is engaged in some activity and the other is idle, stay with the busy one. This is called "helping," otherwise known as "hampering."
