Do not feed him cerelac meant for human child. The protein content is less. A pup will reqiure approx 30% protein in his diet as he grows real fast. A year old lab will weigh abouut 25 kg, and a human child, about 10 kgs. Give him a premium dog weaning food till he is 2 months, post wich you can gradually shift to puppy food. Also cerelac contains milk. Dogs generally do not have a ability to digest Lactose in milk and this causes diarieah. Avoid human cerelac. And regarding brand of dog food go in to a premium food like Royal canin, personal experience says that pedigree is not liked by many dogs.
