I know you're all sick of listening. But this time it is the devil dog who needs training. He has done nothing wrong, well nothing out of the ordinary, for him. It is DH who needs training or possibly shooting, out of kindness of course 
I was in a different room. I heard him tell 8yo dd1 to bring Devil outside. Devil did not want to go out. He growled. Dd1 knows she is not to handle the dog if he challenges her and should go and get an adult so she wanted to leave it. DH thought she was defying him and despite the growling shouted at dd1 to get the dog out. I stepped in at the point and told her to come into the room I was in (getting dressed and there is an open window on the stairs with workmen in the alley so I couldn't go out).
DH then went to remove the dog, who did not want or need to go out
. Devil growled. DH did not listen. Devil up his game and started full on snarling, sounded like it was teeth bared, ready to lunge snarling from where I was.
I interjected again and told DH that the dog was going to bite him, no doubt about it and he needed to either a) leave him as he didn't want to go out, b) go and get some cheese and coax him slowly or b) pop a house line on him, if he could get close enough, lead him out and then give him cheese for 'obeying'.
DH informed me that he should not have to give the dog cheese to get him to behave. This is despite the trainer and myself and my Dad all telling him dogs will only move if there is something in it for them and there is nothing wrong with 'bribing' them with treats. The dog must have scared him as he did change his tone and tactic and did manage to get the dog to go out without being bitten.
We then had a screaming row about him trying to get our child to handle an aggressive dog and about him putting the dog in a situation where he will bite despite me explaining many times how to handle him without causing him stress.
How do I get DH listen without resorting to loosing my temper and swearing when he resorts to his usual point blank answer of "The dog should not be here if he is aggressive, you need to start putting the kids first and not the dog"
Is there anything on the interweb I can show him that will show him why it's best to get the dog to work for treats and why his growling is not a show of dominance or a sign that he would be dangerous if he is correctly managed.
DH is going to get himself bitten if he is not careful. Which, to be perfectly honest, does not bother me
, it would be his own fault. It concerns me that he is putting my child in the firing line.
As an aside the dog will go to the door and ask to be out if needs to go. Dh is obsessed with him going out every so often as he must need a wee after x amount of time.
