Hi NM
Yes I saw the thread title and thought " oh no, what's the bitch done now to our gallant hero ? " .
I only know as a Postman I hate little Jack Russell's , snappy , bitey little things , but a lovely Golden Lab. , you'd be hard pressed to find a nasty one .
Trouble is I can't help you with your problem , I think Nick is a dog man , and I'm fairly confident that when others get home from work they will be able to help you .
Keep ducking and bobbing , and get your jab going .
