Keep your mixed breed in good shape by measuring his food and feeding him twice a day, rather than leaving food out all the time. How much your adult dog eats depends on his size, age, build, metabolism, and activity level. As a general rule of thumb, you can estimate how much he needs each day based on how much he weighs:

Less than 10 pounds 1/4 to 1/2 cup
10 to 15 pounds 1/2 to 1 cup
20 to 30 pounds 3/4 to 1.5 cups
30 to 40 pounds 1.5 to 2 cups
40 to 60 pounds 1.5 to 2.5 cups
60 to 70 pounds 2.5 to 3 cups
80 to 90 pounds 3 to 4 cups
100 to 150 pounds 4 to 5 cups
More than 150 pounds 4.5 to 6 cups

Of course, dogs are individuals, just like people, and they don't all need the same amount of food. It almost goes without saying that a highly active dog will need more than a couch potato dog. The quality of dog food you buy also makes a difference--the better the dog food, the further it will go toward nourishing your dog and the less of it you'll need to shake into your dog's bowl.

It's a good idea to consult with your vet if you're not sure how much to be feeding your mixed-breed dog. And if you're unsure whether your dog is overweight, give him the eye test and the hands-on test.

First, look down at him. You should be able to see a waist. Then place your hands on his back, thumbs along the spine, with the fingers spread downward. You should be able to feel but not see his ribs, without having to press hard. If you can't, he needs less food and more exercise.
