PeterC said:set it up. bolting is the number one reason for dog getting loose and getting hit by a car. serious stuff.
set it up. attach a long line 15 feet or so. Play with the dog in the garden or yard and get it used to it. Make it forget it is wearing it. Play with the dog.
Now, get your friend to open the gate and make sure you have something very enticing on the other side of that gate.
You have the other side of the long line are you are ready to correct. Make sure the dog has a pinch. NOT a choke. This correction has to be EXTREMELY meaningful or you are wasting your time.
As the dog bolts, AT THE GATE LINE (VERY IMPORTANT), YOU CORRECT THE DOG HARD AND SAY, "NO"!
Dog must associate that gate line with YOU being very angry and harsh correction if it ignores your command. It also tells the dog, YOU have control.
A e collar works to a degree and works well on softer dogs. However, a very high drive dog, espcially dog aggressive pit bulls with high pain tolerance will always require a long line. Always.
Pretty easy actually. Timing timing timing and your willingness to set the scenio up is the key.
I am going to steel this info and try this.Thanks!!!
