Your problem is very fixable. It will take patience and dedication on your part to retrain the dogs behavior into a positive response when she is called. The success of this depends more on you and your dedication to the retraining process than it does on the dogs part.

First realize that obedience classes are a must for the two of you. It will help to strengthen the bond between the two of you and will establish you as the alpha in the pack. When looking for a class to enroll in, I strongly recommend finding a trainer who either clicker trains or does positive training and teaches competitive obedience. A teacher who teaches competitive obedience is one who is current with most of the latest training techniques and on what works and what doesn't work. Most use the NILIF theory.

Second, begin consistent and several times a day recall training. This is sometimes referred to as the "come" command. This training process should start in the house where the problem is not associated with in any way. Make sure you have lots of very enticing treats on you before you start your training session.

Take a 10 to 15 foot leash (not a retractable one) and from about 2 feet away from the dog give a "Gracie, Come" command. Don't run the command together but pause ever so slightly after the name. By saying the name, you are asking her to pay attention to you as you are about to tell her what you expect of her. Then very clearly give the "come". Say it in a happy upbeat manner. If she comes, immediately (you can not hesitate on the reward) give her a treat and praise her. Let her know she did right! If she doesn't come immediately, give her a gentle tug with the leash and coax her to you. The key here is gentle. Don't drag her to you. It has to be her decision to come to you. It is your job to make her want too! That's why the treats have to be very rewarding. After the gentle tug, if she comes you want to again immediately (no hesitation) give her the treat and praise.

If she doesn't come with the gentle tug then forget the exercise for this time period. However, she does not get any treats or even her kibble. Some people think this is cruel but it won't hurt the dog to go without for awhile. It may take a day or so but eventually when you go back to the exercise you will have a compliant dog ready to learn. Of course it won't realize it is being taught since it will only be worried about the food.

Remember, this exercise is only done in the house for now. After you get a consistent response every three times, cut back on the treat to every other response but never give up on the praise. You can gradually begin to increase the length of the leash out too. Then once you get 5 consistent responses from at least 10 feet, you can lessen the treat to every third time but again never give up on the praise. Your goal is 20 consistent successful recalls in a row. If she messes up on number 10 or 15, start over again. You must have a consistent recall of 20 times in the house. If you achieve that goal in the house, you can try it off leash. If you have problems then she isn't ready and you must go back to using the leash. After she is doing off leash in the house, you are ready to move outside.

When you are ready to move the exercises outside, realize you are basically starting the whole process over again but it is happening outside now. There will be more distractions and more desire to not listen but if you follow the steps you did inside, you will succeed.

I hope this helps you. Please check on the obedience classes in addition to the above recall training exercises. If your trainer teaches the "come command" differently, follow their instructions but make sure you don't progress without making sure the dog fully understands what behavior is expected. Some trainers progress through exercises too fast before the dog has "caught on" completely.
