Hi, We have a 4 year old Alsation, in the house she's fine but i'll make a list of stuff we need to work on. -Goes mental when there's a knock at the door -Hates men -When you take her out, she'll bark if someone's walking past but once out she doesn't bark at passers by. -Don't trust her off the lead. Is a course a good idea? I've been reading stuff about courses which vary a lot, so a bit confused really. She's learnt to sit in her bed when someone goes out as we'll put a treat in front of her & tell her to leave it. But if someone knocks there's nothing that'll stop her from going mad. Tried the clicky thing which again, will work with people she's used to but if you do it when someone knocks she'll completely ignore it. Moving house so hoping the new environment will help, especially as we won't have a really loud iron door knock! Any links would be great. Great forum by the way, i was in a car place today which has a parrot just wandering around, climbed on my shoulder. Amazing creatures.
