My dog has itchy, smelly dark patches & lumps. Could it be mange?

Updated On September 23rd, 2025

Pet's info: Dog | English Mastiff | Male | neutered | 5 years and 6 months old

Hi, I got my mastiff Oscar back from being taken to the pound by the people that were supposed to be looking after him so I'm not sure how long he has had this. But I've started noticing huge dark hard patches on him. He's so so itchy and smells bad too. I've also taken a close look at him and found a few lumps in random spots I'm really worried part of it is mange and who knows what else. I really don't have a lot of money what should I do?

Those spots on Oscar could be several things including fleas, allergies, skin mites, bacterial infection, ringworm (which humans can get) or endocrine disease. There are a couple things you can do at home and they can help but they may not address the underlying cause. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. You can wash the lesions once a day (not his whole body, just the lesions). Also protect the area from trauma by having your pup wear an elizabethan collar at all times. If the lesions do not start improving within a week or if they are getting worse, have him examined by the veterinarian. I hope this helps and please feel free to post any additional questions.
