My dog Prissy she is a 4 year old rat terrier and she barks and growls at big dogs, she will scratch me and try so hard to get to them. She will claw me up when we driving in the car if she sees a big dog and she tries to jump out of the car to get to them. If one comes in the yard when she is out she will jump on it and it will jump on her, she is a very small dog so I am very scared she is going to do that one day and the dog will beat her up. I am taking her to dog obedience classes but they havent helped yet. She also doesnt want me to get out of her site, If i leave her site she will cry. If anyone has any suggestions on what I can do about her barking it would be appreciated, It gets very frustrated at times with all her barking. I spank her and that doesnt help. The trainer that is doing her dog obedience classes says clicker training might help. Anyone ever tried that and do you think it will help her.
