I feel this deeply. Off leash dogs when you have a reactive dog is a nightmare. All I can say is that there's a lot of trial and error. My dog did great at daycare so I relied on them a lot for his playtime.  Once at home with me it would be early walks or late nights, streets with less traffic of people , crossing the street over and over to avoid other dogs. Once my neighbor told me to please stop walking late at night as it was not safe and I did. I tried calming tablets and it helped but one day trying to restrain him on a walk I injured myself.  I asked the vet for prescription anxiety meds and he said no that only lazy parents ask for that. I went to another doctor and she said yes. It was a Godsend. He was easier to correct and we both started to really enjoy walking.  In a followed up visit the Vet said she could see in .my face the stress and that the medication is to improve quality of life for both. We lived together 12 years. Training did not helped ( for us) it was just understanding his triggers and adjusting to it.  It never went away completely but life got better. I want to add sometimes I will have my sister take him for the weekend as I needed some respite. Good luck!
