I am a vet technician and scabes or sarcoptic mange is very contagious. We see it in lots of stray dogs and some household pets. It can be transmitted to humans just by petting the dog or from humans to dogs. It is so easy to treat in dogs because all you have to do is give an injection of ivermectin and the mites die. My son caught it years ago and we used a lotion with lindane in it which is now banned I believe. The cream sounds like the way to go and lots of cleaning. Good luck.
