"Pink hairless patch & itching" - Looks like a skin related issue, could be something like excema or something else due to dry skin. Consult with a vet to find out the best possible solution for it, maybe they can prescribe some medication or ointment. One thing I'd like to add...don't overuse stuff like dog shampoos or soaps available in the market, many contain strong chemicals that are irritants & make skin dry. Natural substitutes r much better for the dogs...

Hey Anshu...a dog needs non-veg content in its food else its early development suffers. Though, this is not the rule...try going for a balanced dog food (Pedigree) and pay close attention to grooming. If its ticks, or flaky skin, regular grooming alongside a dog shampoo should solve the problem. If however, the problem accounts to ulcers, or bile accumulation through the body..better a vet have a look into it. Explain the situation properly and follow all the procedures. Delay here, and continued itching could affect the dog's coat (shine and thickness) and leave flaky and dry skin all over. Cheers. Prady.
