Perhaps your husband was moving his hands in a way that sparked the dogs prey drive.

Was your pup on a long line? If not, keep him on a line even when running around the yard.

If he jumps and grabs, you can firmly say 'No!' (not shouting), and redirect him off you with the line. If you yell out, the pup may take that as a challenge or an invitation to play even rougher. Once he's off of you, you can step on the line to prevent him from jumping again, or hold the line very close to you, to limit his movement.

If he is playing rough, you need to calm him down by moving into a brief training session. Teach him 'touch!'; this is an easy one to teach, most dogs like to do it, and it provides a means for you to get back into control and for your pup to calm down a little. Again, keep him on a long line all the time when you are outside...

I would get the Marker and Michael Ellis.

If there was ONE single video to purchase besides the pack structure (which I am keeping) which would be the best? "Training with Food", Training With Markers", or the Michael Ellison one? Sorry, not sure if that last one is the correct name. I can actually afford 2 more if I hold off on a behavioralist.

Get the Training with Markers first. You need to have a solid understanding of marker training before you get the Michael Ellis DVD (which is Training with Food)

So, it's the video titled "The Power of Training Dogs
with Markers DVD", right?

That's the one...

Thanks, and to answer a few other questions, no, he was not on a long line this morning, but usually is with me anymore. My husband was digging in the yard, but had been doing it for quite awhile before he bit. Toby is crated at night in our bedroom and in a much smaller crate downstairs when we go out. When I crate him when I am home, he whines and howls. I don't let him out when he does that, but he seems to sleep better out of the crate at those times. What should we do when he growls and pulls at strangers - for now?? I know that the marker training and pack leadership will eventually help with that. I'm very nervous about walking him now, and I'm sure he senses that.

Not to add more to your plate, but another area to familiarize more with would be reading a dogs behavior. I have always found that it is valuable to know what those ears, eyes, tail, body, posturing, etc. are telling us. It really helps with the training, and eliminating unwanted behavior before it happens.

Not sure if there is a podcast or article on here...

Is there a route you can take with very few or no people/dogs on it for now? You being nervous walking him reinforces strongly to him that his reactivity to strangers is appropriate and necessary -- that he is not only not led by his pack leader, but is in fact the responsible one in all encounters. (Sounds like over-simplified jargon, but it has become a cliche because it's so true. )

He needs both a leader-in-charge and gradual desensitizing to other people around him. When Steve and Randy mentioned that he has too many triggers thrown at him too fast, this would be an example.

Ideally, however you can work it out, you could walk him where the other people are outside his zone of reactivity: visible but not close enough to trigger him. With purposeful and calm moving on past, no time allowed to focus and stare and growl (but no nervous hurrying, either) ... just calm "march on by." (There are other MOs too, such as basic ob work done as the stranger passes, but we are throwing so much at you .... )

Also, can you describe the scenario: Are you walking towards the stranger or is the stranger up ahead, with back to you?

And I asked before but missed whether it was answered, are you now using a prong on walks?

"The Other End of the Leash" by Patricia McConnell is an excellent book on body language and behavior.
