I tried cleaning my dog but not make differece. My Dog skin is like out some oil, it always itch
You should bring your dog to the veterinary clinic. They know how to treat dogs with that kinds of problems. You got to hurry do. My last dog died because of my negligence. Don't wait for the worst to happen. Good luck.
Maybe your dog have mange, Here in the philippines we inject ivomec and the itch will be gone for good and sometimes just for a while. The dosage will depend upon the weight of your dog.
