Hi Guys
Thank you so much for responding!
It is great to hear that perhaps the situation can be sorted out! I've been so worried that it has reached a point of no return. The thing that worries me most is the snapping. I dont know how to get round that at all.
SMEAGLE - I admit that she is forever pushing the boundaries (I expected nothing less from a Sibe lol) but perhaps the rot may have set in when she came back after escaping, I did feel so sorry for her (she probably saw this as a complete sign of weakness). Also my boyfriend is living here now... would this have confused matters for her? She did used to listen to his commands but has also started ignoring him aswell as myself. I'm located in Birmingham, UK, and have considered consulting a behaviourist, if I was better off financially I would have one here in a moments notice, but I'm struggling at the moment. I am due to start some part time work in a couple of weeks but am worried that her behaviour may deteriorate further when I am away more in the day. It seems to be a vicious circle.
SARAH & ZEBEDEE - She will do sit, lie down, give paw, go to her bed etc for treats. She is very food motivated lol! I guess my main concern is the snapping, and also trying to get her to walk better. As it stands I find it a nightmare to walk her, as does my boyfriend, and therefore my 14 year old daughter is instantly excluded! She cannot manage her at all. It's a real shame because she used to walk so well. As I say it is a complete battle of wills now, which is exhausting because she is soo strong now.
I had thought about her being led my a stronger male dog who could be "pack leader", but have my doubts. My friend has a German Shepherd cross and they used to play fine. But now she bullies him. She runs in to him constantly and nearly knocks him over, and then he started copying her bad behaviour and ignoring commands when he is with her. He is a very obedient dog who had never before ignored commands!
