Did you see my new thread about this? I think my daughter's dog is the actual cause of the problem so I'm going to have to change our routines when he's around. There's no doubt he's carried the guarding behaviour over to us humans - Paul especially (probably because of the growling/heavy handedness and the lack of solid bond), but I'm sure Bruno's the root cause.
Will check out your new thread today. LOL bit to sleepy last night. Another dog could well be the cause of the problem. Going over to your other thread.
