If the answer to any of these questions are yes you need to invest some time into a little bit of dog behavior training. A little training will go a long way.

 
Dogs that bark can be extremely irritating but the main thing is not to loose your cool, if you shout at him he will try to shout louder than you. Try and find out the cause of his barking. 

Is he barking because he is afraid? 

Is he happy? 

Is there someone out there?   

If you can’t find the reason for the barking then he is doing it because he doesn’t know it is wrong to bark all the time. 

This is where dog behavior training comes in.   

Many dog trainers choose positive reinforcement (reward) as a means of behavior modification over negative feedback.

Most pet owners can’t fathom causing pain to their pet. But even with the ability to control the intensity of the correction, you are still using aversion behavior modification. 

We are talking here about the many products available to help dogs with constant barking, there are special collars which gives them the tiniest of electric shocks so they know that it isn’t good to bark.

On their own, shock collars don’t reinforce good behavior with a positive reward such as your affection, verbal approval (“Good boy!”) or a tasty treat. 

So while a collar may effectively deter negative behaviors like jumping on visitors or running after the mail carrier, it doesn’t reward positive behavior such as sitting patiently or obeying a command to “Stay!”. 

As with any training, you should always reinforce positive behavior with a reward of affection, playtime or a small treat. 

A biting dog is maybe one of the more serious behavior problems, especially now that the laws are tightened and any dog that bites someone is more than likely to get put down.
