I have a cat and 3 dogs. My cat will sleep with me when he can tell that something is up, and demands my lap so I can pet him. My male dog, the one I have had the longest and is the closest to me will stick to me in either depression states or mania. During a mania, he will keep me busy by being active himself and we will do 10-15 miles of biking a day. During depression, he makes me get up, pet him, etc. He is not a service dog, as I am not disabled, but in stores that allow dogs, I have taught him to guard my back side by standing sideways, allowing me to press my legs against his side (sense of assurance). I have also taught him to stand facing away from me to watch for "bad" people. He gets weekly training at a dog training facility as I am going into competition with him, and he is incredibly smart. I am glad I am not considered disabled, but sometimes I feel like it would be easier if he was allowed to come everywhere with me.
