Put on a collar tight enough not to slip over the head. Leave it on for lengthening periods from a few minutes to a few hours over several days. A flat collar for shorthair breeds.
After a few days lessons with the collar, attach a heavy cord or rope to it. Allow the dog to run free with collar and cord attached a few moments at a time fore several days. Do not allow dog to chew cord.
When the dog appears to be accustomed to the free-riding cord, pick it up, loop it around your hand and take your dog for a walk (not the other way around). Don’t stop walking if the dog pulls, balks, or screams bloody murder. Keep going and making encouraging noises. Slap your thigh. If the dog leaps ahead of you, turn sharply left or right whichever is away from the dogs direction and keep moving! The biggest mistake in leash training is stopping when the dog stops, or going the way the dog goes. You’re the leader; make the dog aware of it. If the dog pulls ahead, jerk the cord backward. Do not pull. Jerk or snap the leash only.
If you wish to use a training collar use a soft braided nylon collar that is snug going over the head and rests comfortably high on her neck. When the collar is pulled tight you can anticipate 2 inches of slack for proper fit. Be sure it rests high on the neck where it is more sensitive than the base of the neck so corrections can be easily felt and no over-correction is necessary.
