Yes, puppies can be weaned in 22-28 days and fed with porridge-like liquid food to induce eating, but bitches should be fed for a period of time. You can be completely weaned in 40 days and change dog food in two months. A four-month-old puppy like you has no dietary concerns except that he can't eat foods that need to be taboo, such as ginger, garlic and chocolate. Just don't feed the chicken bones. Bones are hard and sharp, and it is easy to scratch the intestines. If you want to grind your teeth, you can go to the vegetable market to buy the vermicelli bone of that cow and let him chew it when it is cooked. Don't eat it raw to prevent intestinal parasites. In addition, if you are a novice dog, one of the most common mistakes is to feed the dog too much, which makes the dog feel hungry at most. Don't force feed if you don't like it. Such dogs get sick easily. In addition, golden retriever is a medium and large dog when it grows up, so it is necessary to pay attention to calcium supplementation.
