Alsatians dogs dont usually grow a lot of hair so they can be easily maintained, you can feed them like twice a day if they're already grown but if its a puppy it's three times a day. You can feed them Canned food, there are specific can food based on how old they are, There are ones for puppies and grown adult dogs, milk is compulsory to give to a dog when they are just puppies, maybe even golden morn( thats what i gave mine) take them on regular walks to stay fit, Dont give them raw meat. Give them bath once in two weeks, canned food like pedigree, This pedigree is good for a growing dog, The baths are very important too.
But when they're puppies you can just use a wet towel to clean them up with small soap. There's also a soap for dogs too.
