Training a Shih Tzu can be both a fun and frustrating experience. Being a fully human dog, it responds positively to training methods based on praise and rewards. Physical violence and harsh behavior should not be used. Homeschooling is tough. You should avoid giving your puppy the opportunity to have pee accidents inside the house so he doesn't get used to using your carpet. You should never let him wander around the house unattended before the house training is completed, otherwise it is possible that you will step on a pee puddle when you least expect it. If no accidents occur within 4 to 8 weeks after the house training is completed, the task is completed and you can let your dog roam free with peace of mind.
