How do you make a shih tzu coat longer?

To encourage a Shih Tzu's coat to grow longer, ensure they receive a balanced diet rich in vitamins and fatty acids, which promote healthy hair growth. Regular grooming, including brushing at least a few times a week, helps prevent matting and stimulates the skin, encouraging growth. Additionally, avoid frequent trimming and use a gentle, dog-specific shampoo to maintain coat health. Regular vet check-ups can also help identify any underlying health issues affecting coat growth.
