I finally found a puppy weight chart and it has me somewhat concerned and I would like to know if I should be concerned. I bought a postal scale, which should be simple to use, but the puppies keep moving around even thought I did a tare weight with a bowl. The puppies are one week old and range from 2.2 to 6.0 ounces. Every opportunity I try to get my littlest in the lower teats. I am giving Zoie extra calcium and plenty of food and water and whenever I look, the puppies are nursing well. How often should I weigh them and when should I be concerned about my littlest one?
