Weight Gain Rule of Thumb (Puppies)
3-4 Weeks Old, by Tom Schaefges and Harriett Weatherford
A general rule of thumb for weight gain in puppies is that for the first three to four weeks we should expect 1 to 1.25 grams of gain per day for every pound of expected adult weight. So, for example, if we have a breed or breed mix and we expect the adult dog to weight approximately 60 pounds, we should expect the puppy to gain 60 to 75 grams per day for the first three to four weeks of life.
