My neutered 3 yo humps my leg if he has had a particularly yummy dinner (roast beef is fave). Follows me round the house trying to get a hold of me, if he does he humps a couple of times then gets a confused look......
My OH thinks it is hillarious and calls encouragement to him....(Go on my son...)
I have always had females, and they only humped each other when they were both in heat. We took no notice, but when we had visitors, they were very uncomfortable with it, so we let them out into the garden.
Anyone remember the really sad thread from someone who had a neighbour with a collie that never went out, and the owner used to let her other small dog hump its face? Sorry, don't know why I have mentioned that but I often think of that poor dog and feel very sad.
My darling spaniel is far too well behaved for that sort of behaviour. He prefers to just do the arse dragging across the carpet thing when we have guests.
My female was spayed at 6 months too and is a similar age to yours Chickens. She has a 'special friend' that she humps when the mood is on her. She's had the toy since she was a puppy and is totally faithful to it. Definitely humps more when we have visitors of the non doggy variety. Bloody Big Book.
Jas was neutered at 6 months. He's now 19 months old, and just tried to hump my slipper. He hasn't done this ever since he was neutered. Just curious, but, er, is this usual? My MIL is here and it's terribly embarassing trying to dislodge a determined spaniel without drawing attention.
