Our loving Cocker - around 18 months of age, is loving most of the time, we have three children and do make serious efforts to keep their play and him separate and have done since early days due to puppy stage liking to run off with socks, balls etc. However, this last 5 months he has started to become aggressive to the extent I cannot go within 8ft of him eating without him turning on me. He seems to skip the whole growl, show teeth to actually mouthing and nipping. He has bitten myself a good few times now, and other members of my family.
We seem to know the situations he will turn and bite, these are feeding; if he has managed to grab a sock - he does not give it back without trying to nip; and occasionally turning upon being stroked.
We think he is trying to ascertain his status within the 'pack' between us and our children. We love him dearly but we've reached a point we do not trust his reactions. He has bitten, not just us adults, mainly myself and my father, but two of our children, marking and just breaking the skin. We have seen a behaviourist and recommended more intense obedience training. We did complete puppy and next stage training, and I wonder if not playing give and take; removing objects from him in certain ways has caused him to become the way he has. This is the first time we've had a cocker from a pup.
My/our worst fear is we are fast approaching the stage we may have to rehouse to someone whom can train to his needs, our children come first from safety point of view.
Is this level of behaviour extreme, does he have a streak of rage?, can anyone help suggest methods/training or should we rehouse - if we can due to his current biting scenarios...
