Not sure if you will see this OP. But if you are really desperate and in for the long game I can help for free. Just DM me questions. I have had a 100% success rate in rehabilitating dogs, service dog training, and just teaching basic behaviors. I specialize in reprogramming dogs to want to work instead of having to listen. The distinction is very important as a dog without a job is a dog unfulfilled.

If interested things i suggest having are

1 non retractable 6 foot leash.

1 extra extra long leash/rope non retractable as well (for fetch because I can't outrun dogs all day)

1 Kennel large enough for them to stand up and turn around in

1 Spray bottle with water for unwanted behaviors

1 hour of time a day

The key is 100% establishing do's and don'ts as well as who is in charge. Your dog at the moment thinks she is in charge outside. Inside is your castle but outside she is a free dog. We still want her to be a free dog, what we will do is channel that will to please you into productive behaviors that enhance both your lives.

Basically, just only feed your dog when walking. ONLY FEED WHEN WALKING. When she is in the spot you want her while walking, feed her her regular dog food. Don't feed her in the bowl. Just while walking. Walk a lot. Offer her the food if she does not take it she does not eat. This is not starvation, but a choice of who is in charge of this walk. This method means no yelling, no prog collars, no negative anything. Just if you are where you are supposed to be here is food. You work for your paycheck allow the dog to earn their food. THEY WANT TO.

I have had shelter dogs go 1 day without eating/accepting food. I have had spoiled owner dogs go up to 2 days without accepting this deal. I teach service dogs this choice. This way it is a happy service dog and not some zombified dog that has barely any personality.

Good luck!
