Here’s easiest way to communicate to your dog (with this exercise) that you are serious:

Buy a remote electronic training collar. I recommend Innotek or Dogtra.

Here’s how to use it to fix your dog problem:

Follow directions on matching e-collar (remote electronic training collar) to your dog’s temperament.

Next, place a dumbbell on opposite side of room—straight in front of dog-- and also place a distraction toy… off to right.

Send dog to retrieve dumbbell. Let him wear a long line, also. As he starts to veer to right to go after toy, say, “No!” in a loud, forceful tone and then immediately stimulate him with e-collar. Re-issue “Bring” or “Fetch” command and use long line to redirect him back on course, as he may be confused. When dog starts to go toward dumbbell again, immediately begin loud verbal praise, “Good dog, Good dog.”

There you go. Now just repeat this same exercise by altering training location and type of distractions. After a few times you’ll be able to eliminate long line. And after a few set-ups, problem will be fixed. To read more of my dog training ramblings, read about my book (click below): http://tinyurl.com/4efaq

1. The mouth. A dog will always pull has mouth closed tight just before he bites.

2. Body language. The dog's body language will get stiff and still just before he bites. Especially watch stillness. It's very subtle, but at same time very noticeable once you train your eye to look for it.

There are other things that you could look for depending on dog and type of aggression. However, you need to recognize that there are ALWAYS cues... it's just a matter of whether we are quick enough (or aware enough) to catch them.
