What a lot of people do not realize is that majority of dog phobia is taught to kids by their parents or someone who is always around them. Example: You see a child with his mother and a big dog starts to bark and the mother starts to freak out. What she does not realize is that her energy is being transferred to her child. What is her child going to do when he sees his mother freaking out over this dog? He will repeat his mother! That is what I mean about dog phobia is being taught to children. Now as that child gets older, he will relate his bad experience as a child with every dog he sees now. I know that their is that occasional dog biting, and it is hard not to be scared of dogs, but you can do it with patience and some strong nerve.
Always approach a dog without looking at him or paying any attention to him. If the dog is barking at you or approaches you, keep doing what you are doing and pay NO ATTENTION to this dog. That barking dog will start to realize that you mean no harm to him and his barking does not intimidate you. If you show your fear, he will sense your weakness and do whatever is in his power to make you feel scared. Dogs like this are usually terrified of you and are barking at you to cover up their insecurities.
Dogs can sense your fear. If you are scared of a dog, on some cases that dog will be somewhat timid of you. The best way to get over your fear is to find somebody that you know who has a really friendly dog. I mean real sensitive and submissive dog and just take it for a walk. Just have your friend put on the leash for you and just walk over there and pick up the leash with a high level of confidence and take the dog outside and just walk him. When you have that leash in your hand that is the first step into overcoming your fear. Be real confident and be in command and just go walking. If the dog is well trained, then it will follow you and come to realize that you are his pack leader. Also, try carrying a couple of treats with you and make the dog sit and listen to you so you can feel some sort of dominance over this creature. That helps people out a lot when they get comfortable walking the dog.
Most aggressive barking dogs are insecure. You are the human and he is the dog. Just take a deep breath and try to relax. The calmer you are, the calmer the dog will be too.
REMEMBER! No particular breed is a bad breed. Mean dogs happen because of their OWNERS AND HOW THEY ARE RAISED, not because they are just bred to be mean. The old saying, do not judge a book by its cover, same concept with dogs. Do not judge a breed by its reputation. Like pit bulls, there state of origin was to bring down game and to help farmers. NOT TO FIGHT!
Approach this phobia with caution. Make sure you are mentally ready to do this, and make sure that you choose a FRIENDLY DOG to help conquer your fear. If you have to, start with little puppies first and work your way up to the bigger breeds.
