I have a rottweiler dog .when I bought it for the first year he ate much good even sometimes 4 bowls a day along with fire roti but on 4 October 2017 he was hit by any mysterious fever for one whole month he ate not a single bit of food .. doctors dripped him with glucose bottles. After one and a half month the fever left as mysteriously as it came but he was not in condition to eat any puppy food I thought he is a grown up now so I bought him royal cabin adult rottweiler food .. for half month he continued to eat 1 or half bowl a day band left that food too I tried every new company everything. But no effect I even took him to a doctor 200 km away from my house but he also said to serve him meat.. He never are rich meat food nor we can do so as I am belonging to a pure vegetarian family.. I feel too bad for him he is not eating and the expenses on his medicines are ever growing without any effect on him please provide me information to what to do
