Is it safe for my 4-week-old puppy to drink regular cow's milk?

Cow milk is not recommended as it may lead to gastrointestinal upset (vomiting and diarrhea). An appropriate puppy milk replacer, such as Esbilac or Pet-Lac, is recommended in place of cow milk. Warmed milk is also recommended to prevent chill. A puppy likely will refuse cold milk of any kind unless very hungry.

Ideally, they should stay with the mother and litter until at least 8 weeks of age. This can prevent behavioral issues as they get older. They can start weaning to solid foods beginning at about 4 weeks of age. If they can stay with the mother and litter while weaning, this would be best for them in the long run.

No. You can not give Sparky 2% milk. The milk of cows is different form the milk of cows. Also, Sparky is MUCH too young to go to his new home. Puppies should stay with the mother until 8-12 weeks of age. Puppies who are removed too early often struggle with socialization with other dogs and they can have problems with bite inhibition. Sparky will not even be weaned until he is 6 weeks old. Any breeder letting puppies leave the mother at 3 weeks old should not be trusted. Puppies should only be removed this early if there is a medical concern or if they are in danger.

If she is only 4 weeks old she needs to be drinking milk replacer formula. https://www.petsworld.in/royal-canin-baby-dog-milk-400-grams.html You can also start offering some wet food: https://www.petsworld.in/royal-canin-starter-mousse-mother-baby-dog-195-gm.html

Complete, balanced puppy milk powder is recommended as there is always a risk of infections in feeding raw egg products to young puppies. At three weeks he is also old enough to start eating semi-solid food aswell as milk. Soaked puppy kibble, cooked eggs, chicken, fish, rice etc can all be used

Your puppy does not need cow milk and it can actually cause vomiting and diarrhea in some dogs. The puppy can go from mother's milk or a puppy milk replacer (if bottle feeding) right to eating a high quality puppy food. The puppy food can be mixed with some milk replacer in the beginning to make it easier to eat.

At four weeks you can start introducing solid foods, but Blue should still either be supplemented with mild replacement formula or be nursing from his mother. I usually recommend mixing food with some milk replacer in a shallow pan and letting it sit until it is relatively soft, and then letting the puppy explore. Be advised - it will probably be a messy experience at first!
