More Behavior problems

Fear of the unknown is usually a big problem. If a dog does not meet many people as a puppy, he may, depending on his natural disposition, regard people as a whole as the unknown, and react accordingly.

Early training will almost always prevent this reaction. If early contacts are insufficient and the dog is nervous of people he does not know, there is no substitute for slow and careful broadening of the dog's circle of acquaintances, until he has met so many people that nobody seems to be a stranger.

The same approach must be taken if a puppy takes fright at cars, for instance. Non-confrontational acquaintance with his particular fear object will cure the problem. Barking as an Attention-Getter It is not unknown for a dog to use a fear reaction as an attention-getter. If a puppy learns that barking at an object, any object, will result in his owner giving him all sorts of comforting attention, he will very quickly realize that if he wants attention, he should bark, and preferably in an alarmed fashion so he can get instant response from his owner or anyone else around.

Anxiety
There are other, more bizarre, behavioral problems that usually do not involve actual risk to the owner. One of the most common of these problems is the dog that tears the house to pieces when the owner goes out.
It doesn't help just to say that this is another anxiety manifestation. Sometimes the reasons are complex, and the cure always demands considerable commitment on the part of the owner. It should always be undertaken with the supervision of an expert animal behavior expert.

Jumping
Jumping up at visitors and its owner is natural behavior for a dog. However, because some humans find it unacceptable/ it is wise to prevent this behavior by proper training. The younger the dog the easier it is to train. Have your dog on a long training leash fitted to its training collar and set up the situation with a friend. Your assistant should walk in naturally through the door and your dog will bound forward in its usual greeting. Just as the dog starts to jump up, give the leash a really sharp jerk and a stern 'No' command. Follow this with a 'Sit' command, and if this is instantly obeyed, the assistant may praise the dog. This may have to be repeated a few times before the dog appreciates the connection between the punishment and the 'crime'. If your dog habitually jumps at you, the training collar technique is of little use.

The easiest way to stop this behavior is to bring your knee up into the dog's chest just as it jumps forward, and while it is still bemused by your unkind response, give the 'Sit' command, then praise. Once you start to correct jumping-up behavior, insure that your hard work does not get undone by others who might actively encourage your dog to jump up on to its hind legs, whether or not it’s intentional. .
