What is the best way to curb a small dog's fear of big dogs when it extremely effects their manners during walks(ie-trying to nip large dogs)?
There is a possibility the dog, in someone else's care, was either nipped by another dog or in some way harmed or neglected before having any signs of this type of behavior, which began 1 month ago. The dog is otherwise docile and gentle on walks and with both people and small dogs, cats, etc. but, we don't know exactly what happened to provoke the dog's fear or why it occurs during only one activity(walks) and only when noticing a larger dog.
Dog is in good health with no signs of injury.
