Did you ever wonder how to train your Chihuahua to poop outside? Chihuahuas may be difficult to housebreak, but with patience and consistency, they can learn. Start early, set a timer to take them out, and use treats for positive reinforcement. Try the Punctual Method by taking them out every hour, or the 'Poop Here' Spray method to establish a potty schedule. If they make a mistake, gently correct them and take them outside. With practice and patience, your Chihuahua can learn to poop outside.
