Not in a dominant nasty way,but even though I only have 2 dogs I have noticed that Flint does like to be first at everything and Craven lets him. Flint likes to be - First out the door First to any smells even if it means bumping Craven out of the way. He always gets in the car first,and is always the first out of it. He starts whining if they are on lead and Craven is sniffing something he doesn't want to sniff or has already sniffed. If me and Craven are having a cuddle,he thinks nothing of barging in between us. None of this is a problem for me or Craven,but it has surprised me that Craven has let him get away with some things. So for those that have more than 1 dog,who is the leader or the more dominant one.
