HI, I am bringing home my new pup March 8th. I would like to start on the right foot. We don't have a yard. We live in a condo complex. I will be pee pee pad training her. I don't plan on walking her daily which is why I decided on this breed. I would like to give her indoor exercise and playtime. Please advice on how long you exercise your dogs and what kind of exercise. I have read lots of things about the Chi and that they don't need much. My pup should reach around 6 lbs. thanks.
