The itching has a few causes: flea allergy, diet or atopic
dermatitis. My advice is to treat your pet for fleas every month and also change
the food to a diet for sensitive skin and give vitamins for hair and skin for
10-14 days every month. Don’t give him more than two baths per month; if you
don’t see any improvement after 6 weeks, it is better to see your vet. I hope
this information will help you to resolve your dog’s problem.
