Some dog owners think they have a "bad dog." You love him dearly, feed and shelter him, so why does he behave this way?
Training your "bad dog."
Even dog owners with the best intentions may wind up with what they perceive to be a bad dog. You provide all the basic needs for your beloved pet and yet you are rewarded with bad behavior. Unfortunately, the majority of bad dog or puppy behavior can usually be traced back to its owner.
Proper ongoing training is key to achieving good behavior. If you have never tried any basic obedience training with your dog it is never too late to start. There are plenty of great training resources including books, the internet and of course professional training classes.
If you have trained your dog in the past, some reinforcement may be needed. Often times we get lazy and let the occasional bad behavior slide. If your dog or puppy gets away with a behavior even once, he will try it again to see what he can get away with. Don't wait till the behavior is out of control before you attempt to fix it. Make sure you are clear and consistent with what you expect from your dog. Continue positive reinforcement when you catch him doing what he is supposed to. If the problem behavior involves peeing in the house for instance, make sure you praise and reward the dog when he eliminates outside in the proper area.
In some instances you may need to enlist the help of a professional trainer or a behavior modification specialist. Although you had the best of intentions, it could be that you are just not using the proper technique or the technique you are using is not suited to your particular dog.
Have your dog checked out by your veterinarian. Since your dog can't verbally communicate to you that he is in pain, he may be acting out due to illness.
Dogs and especially puppies learn behavior from other dogs. If you acquire a puppy from a dog that was very aggressive, your puppy may display aggressive tendencies. Proper training and behavior modification are a must if you don't want to end up with a "bad dog." Some breeds seem genetically predisposed to certain behaviors so make sure you do your research before you decide what kind of dog best suits your particular situation.
