I was dreading today so hubby took the day off work and I spent the day with my mum. I know this may sound selfish, but tbh, I am completely at the end of my tether and very upset -- didn't want this to rub off on Lily........
Anyway, hubby stayed with Lily, David phoned this morning and said he would call round today on his way home. He suggested she may be coming into season, or that the growling is an expectation of pain rather than being in pain. He also said that her behaviour is abnormal even for a dog with behaviour problems due to the level of escalation in such a short period of time.
When he came, he checked and there doesn't appear to be any signs of her coming into season. She allowed him to stroke her but then growled at hubby when he stroked her. She let hubby put lead and take lead off, but had a funny look in her eyes when he did this. David said we had to make her earn her food - ie, stroke her, if she doesn't growl give her some dinner. He also said she possibly hasn't had enough opportunities to learn good behaviour as we had to ignore her 'bad' behaviour, so wasn't getting any fuss, so becoming frustrated. As he was leaving her said that she is going to be a tough nut to crack.
Since I got home, her behaviour has been very erratic -- she was very pleased to see me, nut growled after a few seconds of me skroking her, she started earning her food, but as soon as it was all gone she went for hubby and she's 'humped' his leg lots of times, but growls when she does this.
I've spoken to her breeder again tonight, have been in regular contact with her since all this began, and there's not much she can really say as she's never experienced this either.
So really, we're no further forwards. We've e-mailed David again tonight re her behaviour and 'humping', but hubby is now where I was last night, and we just both feel that we're completely out of our depths.
We knew that she wasn't going to be an easy 'fix', but we're both at a total loss of to do next and feel that we're failing her.
