You ask so many questions. . .
My family is also a black lesbian~
A four-month-old dog can be fed 3 to 4 times a day, about a paper cup each time. Don’t overfill it, because I don’t know you. According to the size of the domestic dog, if it is too thin, you can fill a paper cup. If it is fat, reduce the amount. If the puppy is too fat, it will be bad for the bones. The dog food he eats is enough for him to grind his teeth. It is not recommended to buy dog ??chews. You can buy pork fan bones and big stick bones for bones. I bought them for 4 or 5 yuan a pound. When they are cooked, you can shave off the meat and give him the bones to chew on. He is very happy.
Don’t give fruits, it’s not good for dogs.
You must not eat chocolate, you will die. Also inedible are onions, green onions, ginger and other seasonings. You can eat some garlic.
Dog food is enough. Now you can basically supplement calcium. Don’t give too much. If you don’t eat soil or poop, you don’t need to supplement trace elements. If you like to cook, you can make your own dog food.
There is basically no need to go to the beauty salon. Labrador is a very economical dog breed. You can bathe yourself, once a month. If it is not dirty, just wash it with warm water without shower gel. It's more comfortable to comb him when you have nothing to do to pet him.
