4.They have sensitive eyes
Because Shih Tzus have bulging eyes, they are more prone to eye irritiations, dryness, and infections. Their long hair can also contribute to these issues, so it is important that you always keep their facial hair around their eyes neatly trimmed. Tear stains may also be an issue due to the size of the breed's tear ducts. For eye irritations and issues, talk to your vet about pet-safe products you can use to keep your dog healthy and comfortable.
