Thats kind of been mentioned. They said that the dog sees himself as second in the pack below DH and then protector of DD and i am invading the space. That i am the one likely to be bitten again before anyone els win the house. However as the dog sees himself as the protector of DD he may try to guard her intensely in the yard so we have to watch that.
DH is building him a bigger pen area in the yard followed by fencing of the back yard more so we can keep the dog and DD apart if required. We are going to try tackling the dog thinking I'm 'nothing' by being the one who controls his food and being more dominant with him.
