I’m glad you have taken some good decisions for your girl. Yes, your vet was right when he has asked you to avoid Milk and chappati or roti in from his dite. Since its been observed that a lot from this particular breed are allergic to milk and milk products and even wheat based eatables. My dog is allergic to both mentioned above and unfortunately it took me really long before I got the right cause of my boy’s constant skin disorder. When all the local vets were pushing down some real strong & expensive antibiotics down his throat suspecting a bacterial infection or mange. My boy was finally relived of his skin disorder after completely cutting down chapatti and milk from his diet.
