You may have inadvertently taught your dog to be fearful, which would actually be the good news, because if you can pinpoint what you did, then you can begin to undo it. Unlike the owner who has food allergies and owns a dog with them, too, or the man who has high blood pressure and so does his dog, what you have is, I believe, a conditioned pattern of behavior, which can usually be fixed. Of course, since most dog issues fall squarely on the shoulders, now is the human’s time for you to do whatever you need to do in order to alleviate your own fears to avoid telegraphing “fear” to your dog. One very common mistake is for owners to tighten up on the leash when they’re afraid. This sends a red alert signal to your dog, who immediately responds by becoming worried or tense. To make matters worse, if your dog had become fearful, and your response was “oh my gosh – my dog is so stressed!”, you’d unintentionally be creating even more stress for the poor creature! Instead, notice the times when your dog *is* relaxed on a walk and praise and treat him for that. If he becomes fearful, speak to him in an upbeat voice, give him a treat when he looks more relaxed, and then retreat from whatever he was worried about. Don’t overstress him by keeping him near something he’s afraid of too long, and take him places where he can have as many positive experiences as possible. In addition, I highly recommend walking with a self-assured friend and her like-minded dog in order to give both of you the confidence you need to walk tall on your own!
