HOW TO TALK SO YOUR DOG UNDERSTANDS...

Everything in language (including "Dog-lish") is based on associations.

And even if we have prior associations with a word, if those associations are not maintained properly, then the word will lose it's meaning-- or association. Or it can take on a different association.

Ever been in a relationship where the words, "I love you" no longer hold any meaning?

In some parts of the world, you can tell a person, "Go jump in a lake" [insert local expletive] ... and the response will garner a chuckle and some back-slapping and maybe a complimentary beer. Whereas in other parts of the world, those same words may garner a challenge to a duel.

Here's my advice:  Start consciously designing the words you use with your dog TODAY, and consistently attach the associations you want with those words so your dog will learn in a few days-- or sometimes-- in only a few minutes--that your commands (your words) have meaning.

Now, you may be wondering about tonation?

The tone is of minor importance.  As a general rule, you should use high tones for praise and lower tones for commands and correction words.

But I can say "No!!!" in a low throaty growl, and if I toss your dog a piece of filet mignon, I can guarantee that by the end of the session, you can do your best to sound low and "growly" ... and your dog will still wag his tale and smile at you and bounce around happily, thinking that he's just done the 'right thing.' 

Because "No!" means ... YIPPIE! I get steak!!!

So-- you need to tug on the leash, firmly, after you say "No!" EVERYTIME... in order to create a negative association with the word, "NO" so that your dog understands and associates what you want to communicate.
