How long does it take to potty train a Chihuahua?

Chi's LOVE spending time with their humans, and that helps with training. But chi's can also be bull headed and strong willed. I had my chi potty trained within a couple of days. Teaching her to sit was also easy, but teaching her down was much more difficult. She saw no point in down, when she was sitting...and when she was sitting she thought she deserved her treat. When training keep it short, and train here and there...that will keep them interested...they do lose interest easily. And if possible make training a game, but be careful if using treats as a reward...chi's do gain weight fairly easily.
