Like that of all breeds, the Miniature Pinscher diet will need to include plenty of animal proteins and carbohydrates for energy, vitamins and minerals for digestive and immune health, and omega fatty acids for coat and skin wellness. This means the best Miniature Pinscher food is premium dry kibble, because it contains balanced portions of the above listed ingredients.
And while premium dog food is expensive, the good news is that your Min Pin won't eat too much of it at once! Each day, depending on the dog's age, size, and activity level, the typical adult Miniature Pinscher food amount is 1½ cups, divided into two meals. Puppies, again depending on age, will need a bit less: about one cup, divided into three meals (not two) until six months of age. For more info on feeding these dogs from puppyhood through maturity, here's a handy Miniature Pinscher feeding guide:

Over the course of a week, with each meal add a little more adult food to the mixture, until the dog is eating it entirely.
If possible, try and stick to the above-listed portions. If constantly overfed (and under-exercised), these dogs will quickly become overweight--and a fat Miniature Pinscher will have joint, breathing, and digestive issues. That same fat Min Pin will also most likely have a shorter lifespan. You can help control your Min Pin's weight by establishing 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, thereby allowing it to eat anytime it wants. It's better to put the dog's bowl down only at mealtimes, then pick it up a few minutes after the dog begins eating.
If you're worried your Mini Pinscher is overweight, try this simple test: run a hand along the dog's side, and if you can't feel any ribs, it's diet time. Reduce the dog's daily food consumption by one-fourth, and add an extra walk, jog, or play period to its daily exercise schedule.
