You shouldn't need to, the Bitch should be capable of making all the milk required from just her food.
Although if there's any doubt about this, you should consult your Vet.
I'm not sure if this is what you're looking for but I know that a dog replacement milk is a milk that can be use to give to puppies when the mom can't produce enough milk or when the mom is no longer alive. Puppies are not allowed to drink milk except for this milk.
1/3rd / One Third of the total number of puppies.
The newborn puppies should be nursing from their mother, they get all the liquid they need from her the first two or three weeks.
Give it at least a year before breeding it.
The puppies pass from the uterus and out the vagina of the mother dog.
I'm not a dog expert but I don't think that giving young puppies water should be advised, let them drink from their mother, if you don't have a mother with the puppy give him milk, unpasteurised is probably best.
1-4 depending on the size of the mother and father
no, you can't give puppies kitty milk mix .
no, because baby formula will give the puppy diarrhea and will cause hem to get dehydrated..
No. Dogs have puppies and Cows have calves. no they can;t but they can give birth to humans my mother is a jack russel, called Patch.
Somtimes yes somtimes no but if the mother of the puppies is dead then yes if the mother of the puppies rejects her puppys then yes if the mother allows her to be around yes. but if the mother of the puppys snarls and growles no take the other pregnet dog away for the mother and her puppys. Female dogs are very moody when they have puppys and very protective, Just like wolves and there puppys!
yes u can its not by law either u can or they have to its your choice but if the puppies are really young let them spend time with their mother and drink the moms milk
