this dog is going to need a LOT more than just an hour in the AM and an hour in the PM .
he comes from working stock , so a dog that is used to being mentally and physically engaged all day .
first thing you need to start with is the engagement with you . like the others have said , " nilif " , and everything comes through you .
educate yourself in the theory and practice of marker training ASAP .
start with short little sessions where the focus is entirely on you for the whole time , even if that means you are stuffing food in his face the whole time . you bring him out , he does his business , work up some quick little drills where you are directing the action , then put him away . repeat that four times in your one hour time slots , and you will soon start to see a dog that realizes all the fun in the world comes from you . these sessions need to be productive , not lengthy .
you can even cut out mealtimes . . . all the food he gets comes from you during your time together .
no more free running the backyard all day . all that unsupervised time is leading him to make his own rules and his own entertainment , which , as you can see , is going to lead to a dangerous situation .
he needs to be crate trained .
don't even think about prolonged behaviours , ( sit , stand , down , stay , etc ) until you / he have engagement . until he demonstrates that he wants what you have ( food , at this point ) and willingly focuses on you to get it , you won't have him in the right frame of mind / motivation to learn .
i'm not in favor of training this dog in a " class " setting . i'd be doing all this foundation work in isolation , before i'd complicate matters with other dog distractions . pretty tough to expect the dog to learn anything from you when , at this point , there are better , more important things to attend to , border collie style . again , remember , this is a breed whose main purpose in life is to monitor and maintain order of the things around him .
as for the biting and nipping , he will use as much force as he feels necessary to " get'r done " , whatever that may be , as HE perceives it .
sorry for the rambling nature of my post . . .
of course , i have to ask , what attracted to you to this breed , and what plans did / do you have for him so that he grows into a healthy , happy dog ?
i don't mean to offend or chastise , but so far , the problems you describe are exactly the kind of BC stories that wind up with the dog at a shelter .
i'll leave you with this bit of border collie advice , " either you find the border collie a meaningful job to do , or he'll create one for himself " .
with this breed , you need to consider what changes you might need to make to your life to accommodate his needs , otherwise the future does not look bright for either you , the dog , or your family . i personally know of one BC who lives happily in a downtown apartment , but the family puts alot of time , energy and money into seeing that he gets the mental stimulation and physical exercise he needs to keep him sane and a livable companion .
if she hasn't already , i'm sure connie will post up the links to the DVD's you need to get this program on track . . . good luck !!
