Question about age?

[HeyJude]

When we first get our pups, we chart them by the weeks for height and weight. If I do this now, Harley will be 9 months in one week. Now, if I go by the month and date he will be 9 months on the 19th. I don't think I need to worry too much about Harleys growth or weight anymore, he eats well and is growing, but I hate to stop the charts now, before he is a year. So, would you go by the number of weeks, or in this case when it is way before the date, or go by the month?

Sounds like this is a question about proper charting. I didn't do that kind of thing with my pup, but as a mechanical engineer I know a little bit about math and graphs

If you're charting on a weekly basis, then you should keep going. There are 52 weeks in a year, so your chart should have 52 points (actually more like 40-44, depending on how old he was when you got him). If you switch now from # of weeks to # of months, the data is not comparable for the same reason you talk about. By the 52nd week, it will all come out in the wash, and you'll agree that he's 1 year old no matter how you count it.

You could get geeky and add a secondary axis denoting months (which I usually do by the calendar) so you could see both # of weeks and #of months all on the same chart (this is something I would do, because it's fun).

As far as general discussions, I talked about my pup's age in weeks until he was 6 months (by the date). Now I talk about his age in months (nearly 8 months now).
