I will repeat my answer from the other thread:
Your dog has developed separation anxiety. You will have to be patient to cure it, but it can be done.
First, you need to buy a crate. Make sure and get the right size. Then leave the crate door open when you are home. Feed the dog in the crate, Put a blanket down on the bottom of the crate. Giver her treats in the crate.
Then you begin the separation anxiety program.
First, you work regularly with your dog on commands such as sit, stay, come. Second, you make sure you dog is well-exercised. Consider taking her to an off-leash dog park. Run her in the backyard with a ball. Take her on a longish leash walk. Wear her out.
Then you begin to accustom her to being alone in the house. Leave her in a sit stay or down stay while you go in another room. At first, just a few seconds, gradually lengthening the time.
Then you stop her triggering behaviors. Whatever your getting ready to leave the house clues are. Does the dog react when you put on your coat? When you take out your keys and jingle them? Start putting on your coat and sitting down or going about your normal chores in the house. Walk around the house with your keys jingling. Do this until your dog does not react any longer to these cues.
Then put the dog outside and leave her and go in the house. Just for a few seconds at first. Gradually lengthening it until you can leave her outside without her reacting.
Then put the dog in the crate with a treat, and leave the house. Just stay outside the door for a few seconds, and then come back in. Keep practicing until you can leave her for a few minutes, then longer and longer.
When you come back from going out do not act excited to greet your dog. Wait until she stops jumping up on you or barking to pet her.
This requires a lot of patience, but it can be done. You may want the help of a professional trainer to keep you on track.
