While water spray in the face is a quite effective method of behavior modification, particularly for barking, when that fails, the next best step is either the throw chain or (my favorite) the rattle can. Basically, a rattle can is a thing that rattles and makes a lot of noise (which dogs generally don't like). The cheapest way to do it is to wash out an empty aluminum can and fill it half full with pennies (old pure copper ones if possible), then duct tape the thing closed. You can shake or throw the thing as a deterent for either the dog or the husband. It is best used when it appears to come from 'God' so that the dog has no idea that you are the source of the correction. It is best to throw the can so as not to actually hit the dog, but in front of or behind. The throw chain is similar in that it is desigend to make a lot of noise with minimal damage. Take about 1ft of that chain that is used to hang lamps, it is light and makes a lot of noise. With a large dog you can fling it at them and not cause damage.
Also of the dog changes from simply barking (protective) at outside sources to growling at them (aggressive), seek professional training immediately.

Okay, Lobo will not bark when he see that I have the water gun or bottle, he might walk away from my reach ( water range) or goes to the other side of the room and does a low bark (not growl) a grunt like he is saying F you. Then he sits down does a big sigh and lays down wacthing me.
My hubby ruin that can idea way back when, so scratch that. I don't know about that chain throwing, Hmm will think about it, okakie dokies. alright later!
