How Much Should A 4 Month Old Golden Retriever Eat. In most cases puppies younger than six months will be fed three times per day. The Golden Retriever pup reaches its adulthood at the age of 12 months to 18 months and should then receive food suited or designed for adult Goldens.

This will minimize transitional stress and digestive upset. At 3 months old a puppy may eat up to 15 cups a day. There are many reasons for feeding your puppy so that he grows slowly while he is under 5 months of age and for keeping him at a fairly lean weight for his entire life.
Start feeding twice a day when hes about 11 or 12 weeks old.
Shell reach half her adult size at this age. By 4 months he should be at 3 cups and up to 4 cups around 6 months. You might feed an adult Golden once or twice per day but your Golden puppy might need to be fed three or more times per day. By the end of week 12 the meal frequency of most Golden Retriever pups can drop down to three a day.
