This is my first post ever. I have a 13 month old male (Angus) and 6 year old female (Heather). They get along well, include some very rough wrestling several times a day. Recently the male has been dominating (or trying too) by blocking the older female from passage around the house and when going upstairs. Sometimes he bites the heavy fur near her tail and pulls her sideways. He generally ends up on top of her biting her again heavy fur near neck. This turns into a wrestling match. She has the ability to resist but doesn't seem to mind. I assume this is teen age stuff on the part of Angus as he is also antsy in general just now. Anybody have any advice? Should wife and I make any attempt to curtail this activity or is it natural growing up? They both have completely free rein in the house, more or less democracy among us.
