Hi everyone, thanks for your advice and kind words - it's much appreciated. However, I'm worried I might have painted a more extreme picture than I intended. I should first give a bit of history about the dog, he was re-homed three times before we got him from the Dog's Trust, and he was only 1 year old. As a consequence, he was very mischievious when we first got him, and he still is now, but to a much lesser extent. My mum wants to get the shock collar to try and correct these bad behaviours - such as, charging up the stairs when he knows he's not allowed to, stealing food off the kitchen counters, stealing socks and running away and wanting to be chased, climbing on chairs he's not allowed on. He has not been savagely beaten by my dad, just a whack on the nose. My dad can often get stuck in door ways and find it extremely difficult to move, and with a dog running around his feet, he becomes despairing and frustrated and will try and get him to move. When he is out and shows signs of anxiety, I comfort him, and then reward him when he starts moving again. However I'm not sure this is the right course of action as maybe cuddling him will only serve to increase his anxiety? He seems to be fine being walked during the day, he will stop a couple of times but then keep on moving. However if you try to walk him when it is dark, he will flat out refuse. I will welcome any suggestions on how to correct his bad behaviours and try and find some info on curing him of his anxiety. He is a beloved and cherished family pet, and he is a very happy and loving dog on the whole. Taking him back is heart breaking and an absolute last resort, and anything that can be done to avoid this I will welcome with open arms. I have spoken to my dad since my first post and he is willing to try training him as much as he can. i've heard about DVDs you can get with car noises and other sounds to condition your dog - is this what people have posted about when they say conditioning and de-sensitising? Please any info will be hugely appreciated! Thank you
