What's wrong with Keji eating wall ash?

Dogs eat wall ash because of the lack of various metal trace elements in their bodies, which is mainly caused by the owner's failure to pay attention to supplementing this nutrition to dogs. Dogs without trace elements will suffer from pica, which will make dogs consciously eat grass, wall ash, soil and other things. Knowing that dogs are caused by the lack of trace elements, we need to find ways to supplement them. Pet owners can go to the supermarket to buy some foods containing trace elements and cook them for dogs, such as visceral foods such as heart, liver and kidney of some animals, but they should pay attention to the right amount and not overdo it, so as not to backfire. In addition, they can also give the dog some nutritious food such as beef porridge and add some fruits and vegetables to keep the dog's nutritional balance.
