When my dog/Shih Tzu was ill, she recommended boiled rice with boiled hamburger and added vegetables- no spices, no herbs, no butter, just plain – add a little to his/her bowl -this is not a long-term deal. My dog really loved it, and I started making my own vegetable medleys for him, and he loved it- and it was healthier than all other things on the market

Purina One Small Breed Plus High-Protein Dog Food

I feed mine Purina Smart One for small dogs. I have always free-fed her, so there is always kibble in her dish. Sometimes I mix in chicken or lean ground beef, boiled, of course, with sweet potatoes, and she loves it. She is a nibbler, so she eats when she is hungry.

My little girl, Pebbles, was all. of 16+ yrs old and just wouldn’t eat the prescribed food. At her age and health, I gave her what she wanted or would eat. I fed her with weight management canned dog food of whatever she wanted. In her last few weeks, she. ate only a hot dog now and then, ground hamburger, 1 time it was taco meat, then she had some green beans and chicken. The last 3 days, she would only eat tuna fish, nothing else. I would add to it. She passed 1 day short of 17 yrs old. I had never budgeted her health care. My vet had a cc on file for Pebbles for Anything she needed for her well-being. I would travel for my work and be gone for weeks at a time. It was to care for her whoever would bring her to the vet. My point is, we do what we can. And when they have had enough, we need to consider that also. No easy fix.

Purina Pro Plan Small Breed Weight Management Dry Dog Food

Mine is on Purina Pro Plan Weight Management for small dogs. I get the chicken-flavored shredded blend with kibble and meat pieces. It has been the best thing for keeping her weight between 10 and 11 lbs. She recently had a lot of teeth pulled, so I softened it for her, and she loves it. She’s 11 years old and has been on it for about 8 years now. It’s the bag with the beagle on the front, and we are on Petco’s recurring order delivery. She gets 1/4 cup twice a day. Treats for her are the meat pieces from her food (I pull some out and bag them up for treats), apple pieces, lettuce rinds (the center pieces of the leaves), and softened carrots.

You can cook fresh meals. I use chicken breast (canned or freshly cooked), brown rice, and canned low-salt string beans. Sometimes I use peas, corn, or carrots instead of string beans. Ask your vet how many calories you should feed him/her and portion it out. One can of each item makes enough for the week, but you can make more at once and freeze it. If you use canned chicken and vegetables, it takes no time at all to put together.

My vet reduced mine’s intake to and 1/8 cup dry mixed with a couple of tablespoons of wet food twice a day. And she only wants him on Purina One. He’s done well and seems happy with it. He’s down to his goal weight and now acts like a dog that’s 4-5 years old instead of 12.

Dogs will eat whatever food is available when they’re hungry. Give him only water and a chew bone for 24 hours. The next day, give him more water and ONLY the food the vet prescribed, and in the portions the Vet prescribes. No snacks. No treats. Dogs are, by nature, opportunist feeders. If you try to mix his old food with the Vet’s food, he may avoid the healthy pieces. NEVER leave food out all day. Feed him twice a day, 6 to 8 hours apart. Remove any food he doesn’t eat. Dogs can only get as fat as their owners allow. Tough love makes healthy pets. Be strong.

Frequently Asked Questions About the Best Foods for an Overweight Shih Tzu

1. What are the best types of food for an overweight Shih Tzu?

The best foods for an overweight Shih Tzu are high in protein, low in fat, and rich in fiber. Look for premium-quality dry or wet dog food that includes lean meats like chicken or turkey, brown rice, sweet potatoes, and vegetables. Avoid foods with excessive carbohydrates, fillers, and artificial additives.

2. How often should I feed my overweight Shih Tzu?

Feed your Shih Tzu two measured meals per day, rather than free-feeding. This helps control calorie intake and prevents overeating. Treats should be limited and counted toward the daily caloric total.

3. Can I give my overweight Shih Tzu treats?

Yes, but choose low-calorie, healthy options such as carrot sticks, green beans, or small apple slices (no seeds). Avoid high-fat commercial treats and use food rewards sparingly to support weight management.

4. Is grain-free food better for overweight Shih Tzus?

Not necessarily. While some dogs benefit from grain-free diets due to allergies, it’s more important for overweight Shih Tzus to have food that’s lower in calories and fat, regardless of whether it contains grains. Whole grains like brown rice and oats can actually aid digestion and satiety.

5. Should I consider a prescription weight-loss dog food?

If your Shih Tzu is severely overweight or has health complications, your vet may recommend a prescription weight management formula. These specialized foods are calorie-controlled, nutritionally balanced, and often contain ingredients that promote satiety and fat metabolism.

6. How can I tell if my Shih Tzu is losing weight on a new diet?

Monitor your Shih Tzu’s weight weekly and check for visible signs like a more defined waist, easier movement, and increased energy. Your vet can also help track progress with body condition scoring and regular weigh-ins.

7. Can exercise improve the effectiveness of a weight-loss diet for my Shih Tzu?

Absolutely. Regular, moderate exercise like short walks, playtime, or indoor games can help burn calories and support healthy weight loss. Always consult your vet before starting a new exercise routine, especially for an overweight or senior dog.
