I need a little help. My first plea for help was when my dog seemed to barking at nothing. Well I feel that the situation is under control, she has moved on to barking at other things. Example she is barking at shadows, mostly sun ray shadows. She also barks out of control at people walking by the house, or people on the street (when were in the car). The windshield wipers, the heater fan. It is just to much to handle sometimes. She'll be a year in April. I hope to put her in dog training classes, do you think that this will help her not to bark at everyone and everything? She is a very gentile girl, and she loves people, but she still barks. My husband will take her to work and all the women at work will go out to see her, but she growls and barks. I really don't want her to be like that. She is a bigger dog so I need her to be that much more relaxed with strangers, and this is very important to me. Any advice or help would be greatly appreciated.
