Ok so doggy daycare and dog parks are complicated topics but I will give you many of my thoughts from a generalized view... But the real takeaway is that not every dog likes or needs daycare or dog parks! Some do and some will love them but for others, it might actually make the issues you are having even worse. Be open and honest with everyone involved (trainer, vet, daycare, and friends that want you to go to the dog park with them) and you will get better suggestions and results!!!
