Cute pup u got there!!
Abt the feeding table. Here is what ive been feeding my pups for the last few yrs.
Avoid milk as a basic feed coz wid most german sheperds milk gives them a runny stomach. However if u mix some cerelac and milk and then give it to them tou its a bit more stable and they dont get loose motions.
As the puppy grows older you should intoduce rice and finely chopped veggies to the feed. One good way of doing this would be to make a soup like feed for him/her. Just add some rice and veggies to chicken soup and give it to him till hes abt 4 months old.
Once the puppy is at 4 months old, u need to start giving him a more solid diet. That includes roti or puppy chow. But i would advise u to give him puppy chow soaked in water or milk.
Hope this info helps!! If you need to know more than pm me
