My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
The fastest way to gain a dog's trust is to obedience train him. Obedience training teaches them that when you say specific commands, you want them to do a specific thing. Once they learn this, they gain self confidence and have less fear of what a human might do. It also tends to make a dog more submissive and see the owner as the boss or leader. Dogs do not bite their boss ever. They do bite people they are scared of and to reprimand other members of their group when they do something the dog doesn't approve of (because they think they are the boss). Do having him submissive helps with the biting if it is due to dominance.
It doesn't have to be formal classes but does have to be on a formal schedule every day at the same time approximately.
The following site is helpful in helping owners train their dog. Be sure and click on the link to the page on obedience at the bottom. and links on subsequent pages leading to detailed instructions.
Training works best if you train at least 30 minutes a day (two 15 minute sessions). I would start making your dog work via the Nothing in life is free program (NILF). It is outlined below.
A strong recall (come) is a necessity.
Many dogs don't come when called because they have learned that the only time they are called is when fun time is over. People call their dogs to them to make them come inside or to stop chasing prey (cats) or to be put on leash (end of free running time) or even crated. The only association they have with the come command is negative.
Additionally, dogs find chase to be a highly amusing game and have learned that if they get close to a human, the human might chase them. They love a good game. So what you need to do is make coming to you more pleasurable.
The easiest way is to reward your dog with small tiny treats and praise whenever your dog comes to you when you give the command. Do this even when the dog wants to come to you. After a few treats, the dog will associate coming to you with getting treats and praise. Outside, you will want to use a long lead. Do not drag your dog to you, but say the command and if the dog doesn't come, give the leash a short tug. Start with short distances and gradually extend the distance as your dog becomes more familiar with the command. Over time, you will reduce the treats and increase the praise until praise is the only reward. Another thing to remember is to never call a dog to you to discipline it, go to the dog. During training I don't call a dog to me unless it is going to be pleasant for the dog. I usually don't have much of a problem since the dogs quickly learn that I have thinly sliced hot dog treats just waiting for them to obey me.
I alway recommend starting inside since most dogs are more than willing to come when inside. You can even have a helper and both call the dog to them in turn rewarding the dog for coming to you.
