First of all, puppy proof the part of the house accessible to your dog during the day. Remove shoes, electrical wires, clothes, ropes, curtains, aupolstry and anything that is loose and a possible target. Cover the floor with old blankets for him to lay on (and take his anxiety out on). Put bitter apple or similar product (Vaseline mixed with cayenne pepper)on table legs and other non-moveable items that you don't want chewed.

Leave something with your scent on it that you don't care if he destroys like an old Tee Shirt so he can access your scent. When he destroys something of yours it is not to spite you. To him the scent of you is like looking at a picture of you. Rub your scent (from your underarms if you must) on his stuffed toys.

When you leave him in the morning leave him with something to do for the first half-hour. Studies show that most damage happens within the first fifteen minutes. Leave him with a knucklebone or a Kong toy filled with peanut butter.

When coming and going don't make a big deal, a mere see ya later and hidy ho will do. Don't pay attention to his big show, he will try to pull your heartstrings and he knows them all. Give him a half an hour to cool down after you get home, then call him over and give some lovins.

 

Digging can be handled is several ways.  One way, and I have seen this work, is to bury their poop in the holes.  I believe this works when you have a dog that is digging to bury stuff.  When they go to find their treasure, all that comes up through the soil layer is poop smell. Another remedy for digging is to rope off an area in your yard where your dog can do whatever he wants.  This works best when you can be there to catch him digging and not let him out alone until you feel he has earned your trust. Quite simply you show him the place, let him go about his business and when he starts to dig up the lawn you ambush him with "NOOOOOOO!!!", you immediately take him into his new area and tell him "This is where you dig" and show him by digging around yourself in there. If he starts digging, tell him good boy. Repeat this around 100 times. 

Sometimes dogs are digging to get under a fence, in this case surrounding the obstacle with lava rocks and keeping his nails short is the best answer.  He could be digging to cool off in the cool under soil.  Perhaps he needs a shady spot to rest and/or a sprinkler (an old hose with a pinhole works great, our dog Apollo loves it). 

 

 

Tugging on the leash is your dog's attempt at testing your power and it it also helps to fulfill your dogs need to exercise his jaws. To remedy this problem we must address each of these issues, starting with the later as it is the easier.  Get your dog some good pressed raw hide, dentibones, and kong toys. Take an old dishtowel and dip it in chicken broth, tie it in knots and freeze it.  This is a wonderful treat for your teething "little" boy. 

The other problem is not so easy.  You need to assert yourself as higher than he in your house caste.  He should be obedience trained by you every night for at least 15 minutes and taken to a class if you can.  With this training he should start to view you as having a little more authority.  Now we can address the actual offense. Start off by getting yourself some hot sauce and spread, not too much, on the his end.  Again I stress, just enough to make it hot, it shouldn't be splashing around.  He bites on the lead, you say NO in a stern voice, and he receives a hot tongue. Repeat as necessary. Make sure to praise him when he is not tugging at the lead and whenever he is doing something that you want him to do. 

You can replace the hot sauce with any number of corrections (shake can filled with coins, squirt bottle, even a good leash correction) but the important part is that you accompany your corrections with a firm NO and use his name when you tell him. 

You must be consistent with him and never let him win, he doing more than tugging at the leash he is positioning himself to take over the household. this dog should also be given nothing for free, he should sit for his food, he should sit to go out, and he should be the last one to go through the door, and the last one in the household to eat.
