Can anybody help? What can you do with a bitch that scent marks just like a male dog. But not just wee. Poo aswell.
Actually witnessed her "cocking" her legs (sounds strange. she did like a handstand, which meant that both her back leg were in the air!!) up against my daughters full length curtains.
She also will scent on anything that has just come off the washing line and is at floor level.( got wise to that one though)
But what is really more annoying and embarressing is if I take her to a new environment ie visiting with me, she will scent with poo!!!
She is 15 months old and not spayed.

The answer is same as for males, supervision and training. 

It may be helpful also getting to the root of the issue (uncertainty in strange environment).

Most of my more dominant bitches scent mark, but apart from forgetting themselves when in season arriving at the stud dogs premises have never marked indoors, or my belongings.

Ditto, all my bitches have scent marked but NEVER indoors.
