My pet has been itching for months. We have put him on antibiotics, anti fungal treatment before but that didn’t work. We have used medicated shampoos as well which didn’t work. We have changed our floor cleaner to pet friendly but yet still the itching continues. Can anyone let me know what may be the reason. He self bites himself so much that it makes me sad that I am unable to understand the problem and treat him well. My pet is 9 months old now. He had parvo when he was 2 months old (not sure if any heavy medications caused this) He mostly eats Rice, lentils, paneer, chickpeas, chicken etc as recommended by vet.
