By Dr Laura van Dalen. By the time that you take your puppy home, he or she will be weighing about 12-15 pounds. We feed our puppies Pro Plan puppy large breed Formula, chicken flavor. You can find this food at PetSmart, Petco, Chewy, Amazon, etc. At 7-8 weeks they usually eat about 3/4 cup 3 times a day. By week 10 he should be eating about 1 1/2 cups 2 times a day. This amount increases rapidly as the puppy grows to about 3 cups for females and 4 cups for males twice a day by the time they are 7-8 months old. As their growth rate starts to slow down, so do their food requirements. You should start decreasing the amount of food until your puppy is about 2 years old and keep him in good body condition. Use common sense. If your puppy/dog is too fat, then feed less food. If he is losing weight, then increase the amount of food. If you prefer to feed your puppy 3+ times a day, you are most likely going to end up having problems potty training him. Most puppies like to release themselves after they eat, so the more times a day you feed him, the more times a day you are stimulating his need to eliminate. A 10-week-old puppy needs to eat 2 times a day only. However, the important thing is how much food he is getting through the day. Split that amount into 2 or 3 parts. Keep him in 2 meals a day until he is at least 1 year old or keep this schedule through your dog’s life. If you have a very heavy puppy, you should feed less food. Remember that heavier puppies are more propense to joint problems.
