i would never go by the charts honestly i think it just depends on the dog.
i got skoshi at 8 weeks at he was 1pd 9 oz and when he died he was at about 7pds and not over weight at all. They are actually get a certain amount of food.
I think it depends on the dog and their backgrounds. also their energy level.(which still would prove wrong for skoshi because he was hyper non stop)
i dunno but the charts have been proven wrong many times
