Hello Fakid, I didn't know anybody in India have Cane Corso. Where did you get the Puppy from? Could send me the photos of the Puppy to me at email@example.com
I always wanted a Cane Corso and only way to get a quality breed in India is to Import.
About the sickness: Where do you keep him? Inside or Outside. When did you get puppy? he might difficulty in adjusting to the climate, as it getting warmer here. Give 24 Hours water. What do you feed him with?
