How do you potty train a shih tzu to go outside and potty?

To potty train a Shih Tzu to go outside, start by establishing a consistent routine, taking your dog out first thing in the morning, after meals, and before bedtime. Use a designated spot outdoors and encourage your dog to eliminate there with a command like "go potty." Reward them immediately with praise or treats when they do so successfully. Be patient and consistent, as accidents may happen; clean them up without scolding to avoid confusion.
