Just like with people, dog behavior doesn’t always have a logical explanation. Dogs can sometimes dislike a person for no apparent reason. You can make your dog happier to see those he illogically dislikes by making sure their visits are associated with something pleasant.

Some suggestions

Ask the person not to stand directly over your dog in a dominant position. Instead, ask them to approach from a sitting or kneeling position. Supply the disliked person with a special treat that your dog particularly loves, and have only this person give your dog that treat. Have the person avoid making a fuss when they give the dog the treats. Making a fuss can cause your dog to become more nervous. Once your dog associates the treats with the disliked person, the person can begin to give your dog simple commands with the treats as rewards. Over time, your dog should come to accept the person and may even start to like them.
