Good for you!!!
I'm so glad you've made that decision!
I really hope that things work out well for you! Basic obedience classes will NOT be a cure all...but they are definitely a start in the right direction! Are you doing an obedience class through a private training facility or through like
petco or
petsmart or something?....just asking b/c a private trainer may be more helpful with your specific training problems than a trainer from a petstore. Ask them for tips and suggestions with the bolting.
If you can, I would try working with him for a little each day on a leash at doors (you can start with inside doors if that makes things easier)...make sure you have a good grip on him....have him sit, then simply open the door or window....second he goes for it give him a pop, tell him sternly "WAIT," and then shut the door...repeat until he DOES wait, then step towards the door yourself...if he moves tell him "WAIT" again, shut the door and try again....repeat until he's waiting long enough for you to get out the door....once he's to the point of sitting and waiting until you are out the door....then you can give him a release command of "OK" or whatever you choose to use and that means he's allowed through the door. Do not EVER allow him through an outside door before you! Do it once and you blow the training (same goes if the kids or hubby do it!)!
For windows I'd wait till you start some leash training...once he's ok on a leash this is how I'd work with him....open a window in a room that he's not currently in...put him on a leash outside the room and then bring him in and try to walk past the window from a good distance....if he tries to approach it at all tell him sternly "NO" and give him a pop then praise him if he looks away from or ignores the window. If he starts doing well with that move him closer and closer to the window walking PAST it without stopping. Once he's able to walk past without reacting to it....start slowing down in front of it to give him a second to consider it....again if he tries in any way to go for the window tell him "NO" and keep moving till he stops. Keep working towards being able to have him standing in front of the window without any interest in going towards it.
It will be a LOT of work to get him to stop bolting.......exercise will help decrease his drive to do it...but it won't stop him....he will need training at the doors and windows!
