why does my FEMALE 8 month old beagle try to dry hump a 2 year old lab?

i hav a 3 year old female dog and a 6 year old male dog. my male humps her when she's in heat (but he's neutered). she thinks this is like a game, and she tries to hump him back. either that of she's trying to show her dominance... besides, she is much more smarter than the male and is much more dominant over him. she wears an expression on her face that says, im the boss of this house!!

Dominence.

It's most likely a sign of dominance.

it's a domination thing. This is why you also see males humping males, and dogs humping objects.

Just a case of teenage hormones. She will grow out of this soon.

You may want to think of having her spayed soon. There are enough dogs needing homes now.

She is asserting her dominance over him.

i dono! she wants babies! Lol

im joking! dominance
