My puppy has Sarcoptic mange. Will he get it again? How long before it goes?

Hi my jack russell puppy of 8 weeks has a bad case of sarcoptic mange…i rescued him from living outside in a area with alot of bigger dogs so he has had a rough start to life, i took him in 5 days ago and notcied his skin, someone suggested it be stress related, it didnt clear up so he was at the vets today and we had it confirmed with a skin scraping….he is to start treatment 2morrow by being “bathed” the vet says he needs this 3-4 times….what else will he need?? He mentioned anti bs?? Also how long before he starts to feel better as it breaks my heart to see him in pain the poor little thing…Because hes had it once will he have it again??
His name is patch :-)
I will ask my vet 2morrow any questions i have, unfortuanetly he is a foreign gentleman and he found some of the language barrier a little hard trying to explain the answers to questions i had…..

My daughters Pug had this and it cleared up with the treatments.Stress can be a big factor if it was to come back so keep your baby as calm as possible.Also feed a good quality food with no by-products or grains
