Feeding a Shih Tzu: A Nutritional Guide for Your Beloved Companion

Proper nutrition plays a crucial role in the overall health and well-being of your Shih Tzu. To maintain their ideal weight and prevent obesity, it’s important to provide them with a well-balanced diet.

I recommend feeding your Shih Tzu a twice-daily meal plan consisting of a balanced adult small bite diet. This helps to prevent weight gain and ensures they receive the necessary nutrients throughout the day. Remember to consult with your veterinarian to determine the appropriate portion size based on your Shih Tzu’s weight and activity level.

Dry kibble is preferred over canned food for Shih Tzus as it promotes dental health. The chewing action required for consuming kibble helps to scrape away plaque and prevent tartar buildup. Additionally, opt for high-quality dog food brands specifically formulated for small breeds like Shih Tzus. These diets are tailored to meet their nutritional needs and provide optimal health benefits.

While a well-balanced diet is essential, supplements may be recommended by your veterinarian to support your Shih Tzu’s overall health and well-being. These supplements can provide additional vitamins, minerals, and other nutrients that may be lacking in their regular diet.

Remember to provide fresh, clean water at all times to keep your Shih Tzu hydrated. Hydration is key to maintaining their overall health and promoting proper digestion.

Feeding your beloved Shih Tzu a nutritious diet is a vital part of their care. By following these guidelines and consulting with your veterinarian, you can ensure that your furry companion receives the nutrition they need to thrive.

Shih Tzu Grooming Guide

Grooming is an essential part of caring for your Shih Tzu, especially when it comes to their long, beautiful haircoat. Regular grooming helps to keep their coat clean, free from tangles and matting, and prevents skin irritations. In this section, I will provide you with a comprehensive guide on how to groom your Shih Tzu, including bathing, brushing, and taking care of their eyes and ears.


Shih Tzus should be bathed regularly, typically once every three to four weeks. Use a gentle dog shampoo that is specifically formulated for their sensitive skin. Make sure to rinse the shampoo thoroughly to avoid any residue. It’s important to note that over-bathing can strip their coat’s natural oils, leading to dryness and skin problems.


Due to their long haircoat, Shih Tzus require daily brushing to prevent tangles and matting. Use a slicker brush or a comb with wide teeth to gently remove any knots or tangles from their fur. Start at the top of their head and work your way down to their tail. Be sure to be gentle and patient during the brushing process, as Shih Tzus have sensitive skin.

Eye Care

Shih Tzus are prone to eye problems, so it’s important to regularly clean and care for their eyes. Use a clean, damp cloth or a cotton ball soaked in warm water to gently wipe away any discharge or debris around their eyes. Be careful not to get any water or cleaning solution directly in their eyes, as this can cause discomfort.

Ear Care

Proper ear care is essential for Shih Tzus, as they are susceptible to ear infections. Check their ears regularly for any signs of redness, swelling, or an unpleasant odor. Clean their ears with a dog ear cleaning solution or a mild, vet-recommended cleanser. Use a cotton ball or a soft cloth to gently clean the outer ear and avoid inserting anything into the ear canal.

Remember, if you are unsure or uncomfortable with grooming your Shih Tzu yourself, it’s always a good idea to seek professional help. Professional groomers have the experience and knowledge to handle your dog’s grooming needs effectively.
