How Much Food Should a Shih Tzu Eat?


Shih Tzus are adorable small dogs known for their playful and friendly nature. As a responsible pet owner, it is crucial to provide them with a balanced diet to ensure their overall health and well-being. Understanding how much food a Shih Tzu should eat is essential to prevent overfeeding or undernourishment. In this article, we will delve into various aspects of a Shih Tzu’s dietary needs, including their daily caloric intake, feeding schedule, portion size, and factors affecting their appetite.

Daily Caloric Intake for a Shih Tzu

Like humans, dogs have different metabolic rates, which means their caloric needs may vary. It is crucial to determine the appropriate daily caloric intake for your Shih Tzu based on factors such as age, weight, activity level, and overall health. On average, adult Shih Tzus require approximately 40 calories per pound of body weight per day.

Factors Affecting Caloric Needs

1. Age: Shih Tzu puppies have higher caloric needs compared to adult dogs due to their rapid growth and development. As they age, their caloric requirements decrease.

2. Weight: Overweight or underweight Shih Tzus may require adjustments in their caloric intake. Consult with your veterinarian to determine the ideal weight for your furry friend.

3. Activity Level: More active Shih Tzus, such as those involved in agility training or frequent exercise, may require additional calories to fuel their energy expenditure.

4. Neutering/Spaying: Neutered or spayed Shih Tzus may have a slightly lower caloric requirement due to changes in hormone levels and metabolism.

Feeding Schedule

Establishing a consistent feeding schedule is essential for a Shih Tzu’s digestive health and overall well-being. A recommended feeding schedule for adult Shih Tzus is to provide two small meals per day, ideally in the morning and evening. This routine helps prevent gastrointestinal issues and aids in portion control.

Feeding Puppies

Shih Tzu puppies have different feeding requirements compared to adult dogs. Puppies should be fed three to four times a day until they reach the age of six months. This frequent feeding schedule accommodates their high energy levels and supports their growth and development.

Portion Size

Portion control is crucial to prevent obesity and ensure your Shih Tzu maintains a healthy weight. The appropriate portion size for your Shih Tzu depends on their age, weight, and activity level. Always refer to the feeding guidelines provided on the commercial dog food packaging, as they are generally tailored to the specific needs of different dog breeds.

As a general guideline, adult Shih Tzus typically require approximately 1/4 to 1/2 cup of high-quality dog food per meal. However, this can vary depending on the brand and the specific nutritional composition of the food. Consult with your veterinarian to determine the ideal portion size for your Shih Tzu.

Feeding Puppies

Shih Tzu puppies have smaller stomachs and higher calorie requirements. They should be fed smaller, more frequent meals. As a general guideline, a growing Shih Tzu puppy may require around 1/2 to 1 cup of high-quality puppy food divided into three to four meals per day. Again, consult with your veterinarian for personalized recommendations.

Factors Affecting Appetite

Understanding the factors that can influence your Shih Tzu’s appetite can help ensure they receive adequate nutrition.

Temperature and Weather

Extreme temperatures, such as hot or cold weather, can affect a Shih Tzu’s appetite. During hot weather, they may eat less due to decreased appetite, while colder weather may increase their food intake to maintain body temperature.

Health Conditions

Illnesses, dental problems, or gastrointestinal issues can lead to a decrease in appetite. If your Shih Tzu suddenly exhibits a loss of appetite, it is crucial to consult with a veterinarian to rule out any underlying health conditions.

Stress or Anxiety

Shih Tzus are sensitive dogs and can experience stress or anxiety, which may affect their appetite. Changes in their environment, such as moving to a new home or the presence of unfamiliar visitors, can temporarily decrease their appetite.

Frequently Asked Questions (FAQs)

  1. Q: Can I feed my Shih Tzu human food?

    A: While some human foods are safe for Shih Tzus, it is essential to consult with a veterinarian before incorporating any human food into their diet. Some human foods, such as chocolate, grapes, onions, and garlic, can be toxic to dogs.
  2. Q: How often should I change my Shih Tzu’s diet?

    A: If your Shih Tzu is on a commercial dog food diet, it is generally not necessary to frequently change their food. However, if you decide to switch brands or types of food, it is recommended to do so gradually over a period of 7-10 days to avoid digestive upset.
  3. Q: Can I free-feed my Shih Tzu?

    A: Free-feeding, where food is available to the dog at all times, is not recommended for Shih Tzus. It can lead to overeating and obesity. Establishing a consistent feeding schedule with portion control is the best approach.
  4. Q: Should I give my Shih Tzu treats?

    A: Treats can be a part of your Shih Tzu’s diet but should be given in moderation. Opt for healthy, dog-specific treats and consider adjusting their meal portions accordingly to avoid excessive calorie intake.
  5. Q: What should I do if my Shih Tzu refuses to eat?

    A: If your Shih Tzu consistently refuses to eat or shows a sudden decrease in appetite, it is recommended to consult with a veterinarian. Loss of appetite can be a sign of an underlying health issue that requires attention.
  6. Q: Can I feed my Shih Tzu a raw food diet?

    A: Raw food diets can be a controversial topic. It is crucial to consult with a veterinarian to understand the potential risks and benefits associated with feeding a raw food diet to your Shih Tzu.
  7. Q: How can I help my Shih Tzu maintain a healthy weight?

    A: To help your Shih Tzu maintain a healthy weight, ensure they receive regular exercise, follow a balanced diet, and avoid overfeeding. Regularly monitor their weight and consult with a veterinarian for personalized recommendations.


Providing the right amount of food for your Shih Tzu is crucial to their overall health and well-being. Understanding their daily caloric intake, establishing a consistent feeding schedule, portion control, and considering factors that may affect their appetite are essential steps in ensuring your Shih Tzu receives the balanced nutrition they need. Always consult with your veterinarian for personalized advice and recommendations specific to your furry friend.
