Hello..my puppy is Maxi kintamani bali dog,there are many brown spot on skin and itchy..vet said he is allergy with dog food..i change it to Taste of the wild and timberwolf..but totw still allergy and timberwolf is rather better..is it scabbies or allergy??
Unfortunately there's no way we can diagnose over the internet based on a description, even if it weren't against this forum's rules to do so. I would be going back to the vet and asking if they can perform a skin scrape, where they look at skin cells under a microscope to see if there are any parasites, fungus, etc. But only a vet who can physically examine your dog can help you figure out what's going on here.
