So rookiedog is 2.5 years old, big breed , neutered when he was about a year old.
Over the past few months he has taken to over-excitedly greeting any female visitors who arrive on the doorstep for a walk with me. Today it was particularly embarrassing as my friend was wearing a light coloured cuddly coat that looked vaguely like a dogs coat. He kept trying to nip at it, after I'd prised him off her legs.
It's not usual for him to behave like this at all, he's normally very placid, he was also quite barky at the start which again is not like him normally but he's been like that a few times the last few walks.
He shows no interest in female dogs.
Any ideas about why he is suddenly behaving like this and also how to stop him ?
