I read that if you have more than one dog they will sort themselves out and decide which one is higher ranking.

How do I know which of mine is or are they too young to have sorted it? What signs should I look out for?

Archies 14 months and Bramble is 5 months old. I can't see any sign of either being "in charge". I thought with Bramble being so young Archie would be higher but he doesn't seem to show signs of it - not that I can see anyway!!
