"i read somewhere on here the other day about when your dog nips you, you are suppose to yell in high pitch and walk away like puppies do in a litter. hope this helps!"
Yeah, but we're not dogs and your dog knows this. Please give him/her more credit. "When in Rome..." You're dog will be just fine learning to "speak" human, no need to regress back to the ice age just to try to communicate w/ an "animal". This is your furbaby, show him what you want and if you feel they then know what you want and they don't comply, they get in trouble for it. And when they're right, they get praised.
Dogs are wayyyy smarter than people give them credit for, I think the most important thing is to remember that they're dogs and we're humans and there's no need to "speak dog", just teach them to "speak human". Yeah, it's very important to know what you're dog is thinking because this will help you teach him/her to "speak human". That's all.
