It is best not to give your Golden Retriever milk, as it can easily lead to vomiting or diarrhea, as well as flatulence or stomachache. Because there is a lot of lactose in milk, this will turn into lactase after entering the golden retriever's body. When the golden retriever just comes out, it will have a lot of this enzyme, which can be decomposed normally. However, as the golden retriever grows larger, the ability of this enzyme in the body will decrease, which will eventually lead to the inability to break down this enzyme, resulting in diarrhea. There may also be milk allergy and vomiting. If you want to add some nutrition to your golden retriever, you might as well give it some goat's milk or yogurt. Because when yogurt is fermented, it will replace the lactose in the milk with other lactose, which can be better digested. At the same time, the enzyme protein will also be broken down, so that milk allergy can be better avoided. Goat milk is more effective than cow's milk, has higher nutritional value, and is easier to absorb. At the same time, its hematopoietic function is also very good, and it can also achieve the effect of beautifying hair and make the skin healthier.
