My dog barks at other dogs and is scared. How do I socialize her?

Continue with gradual introductions. Correct any negative behavior immediately and praise /reward good behavior. Be consistent. You can also try a pheromone product, such as the Adaptil collar or DAP plug in diffuser, to decrease any anxiety.

Gradually introduce her to one person at a time. Do this in a neutral location such as a park. Begin with a short intro from a distance and gradually increase the time while closing the distance. Correct any negative behavior immediately and praise good behavior. End each session with a small reward. As she acclimates to one person, add another then another. Take her to as many public places as possible as well. This will acclimate her further to people and crowds. The use of a pheromone product, such as the Adaptil collar, may help decrease any anxiety. This will take time and patience. Do not rush or force her to meet people, especially if she is trying to run away. Give her a break when this happens and try again once she settles down.

Gradually introduce her to one stranger at a time. Begin with very short visits/exposures. Increase the time as she acclimates. Introduce more people as she accepts them. Offer praise and reward after each episode. A pheromone product, such as the Adaptil collar which can be worn when out or the DAP plug in diffuser to be used at home, may decrease any anxiety.

the best way is the keep exposing him to other dogs. If you have a friend that has a well adjusted dog he could meet first would be best. Let them sniff each other on the leash before letting them play. some dogs act completely friendly and normal off the leash around other dogs than they do on the leash. Once he gets comfortable with this interaction you can progress to other dogs. You can try to find a group puppy class that can teach basic obedience and gets them used to other dogs at the same time.

It would be a good idea to enroll her in an obedience class (even if she is older). There she can learn to interact with people and other dogs in a controlled environment, and there will be an instructor there to help you with any particular issues you're having.

This actually is not particularly unusual - while many dogs enjoy playing with other dogs, some dogs definitely prefer people. The dog park can be overwhelming even for social dogs so I would recommend avoiding it for now - if she continues to feel overwhelmed she could start to become fear aggressive. You may want to start by meeting one on one with a quiet dog friend to get her used to dogs. Make sure it is a good experience by offering treats, and if she starts to become too anxious stop and try again another day. She may never get to the point where she loves other dogs that are not familiar, but hopefully you can find a few dogs that she knows and will play with.

Introduce them to one another gradually. First, by allowing them to hear and smell one another through a closed door, then by sight without physical contact, then supervised contact. You will need to progress gradually through each phase. Correct any aggressive behavior immediately and praise good behavior consistently. A pheromone product, such as the Adaptil collar or DAP plug in diffuser, may decrease any anxiety or aggression.
