The Shorkie Tzu diet will need to contain animal proteins, healthy carbs, vitamins, minerals, and omega fatty acids--nutrients every dog needs to maintain its health in the long term. This means the best Shorkie food is premium dry kibble, as it contains balanced portions of the above-listed ingredients.
And as you can imagine, your Shorkie won't eat too much. Adult Shorkie Tzu dogs, depending on their size, age, and activity levels, will only need about 1½ cups of premium dry food per day, divided into two meals. Shorkie puppies will need a bit less: again depending on age, about one cup per day, divided into three meals (not two) until five months of age.

Try if possible to stick to the above-listed portions. If constantly overfed, these hybrids can quickly become overweight--and a fat Shorkie Tzu will have joint, breathing, and digestive issues and a potentially shortened lifespan. You can help control your Shorkie Tzu's weight by having consistent feeding and exercise schedules, by not feeding the dog table scraps, and by not leaving food in the dog's bowl all the time.
If you're worried your Shorkie Tzu is overweight, give the dog this simple test: run a hand along its side, and if you can't feel any ribs, it's diet time--which means less food and more exercise!
