the following technique is called thrashing your dog. Keep yer shirts on and put the hotline to the spca down.
Thrashing a dog
a new puppy/dog likes to playfully nip. The alpha male and female have to play along by snapping your fingers around the muzzle to simulate a nip while growling, get on your hands and knees to get closer to their level. As the puppy/dog gets a little rougher growl like you are a VERY pissed off dog,grab the dog by the jowls and snarl and snap your teeth close to the neck while roughly placing the dog on its back. That is the submission position for a dog. After the dog yelps and squiggles push it away sharply. Do this a couple of times. After a while when the dog hears that "special" growl, they know they have pissed off the alpha male/female.
Now when the dog is nipping at the boys heel, thrash her immediately, grab the jowls, roll her on her back and snarl. After a while she will realize that although Daniel is "weaker" than her he is above her in the pecking order. After she is thrashed put her nose next to daniel and firmly tell her "bad dog, say sorry" have daniel proffer his hand and see if she will either lick it or instruct daniel to pet her.
shouldnt take too long.
