How can I train my Maltese 3 year dog to behave?
Scolding her insecurities, etc is not the way to go. You need to learn the skills to know what to do and going to training classes will be your best bet. But you have to find the right trainer that deals with only positive reinforcement. I recommend getting a book by Emma Parsons, called Click to Calm (Healing the Aggressive Dog). It will help with desensitize your dog to approaching strange dogs. Using your own body language when under stress as a cue for your dog to remain calm. Find a trainer who is up on the latest in canine behavior. I like the trainers: Patricia McConnell, and also Brenda Aloff. Both are great with aggression. I go to their seminars and just love them. I have seen Brenda Aloff twice and will see her again next year with two other trainers here for 3 days. PetSmart trainers will be unable to help you.
