The poop after a dog eats dog food is black

The poop after a dog eats dog food is black, which means the dog food contains a high amount of meat, which is normal. If the cause is not the dog food, the owner can observe whether there is intestinal mucus in the dog's feces, whether the dog's mental state is not good, etc. If the dog bleeds from the duodenum, small intestine and other gastrointestinal tracts, the dog will also pass black stool. It is recommended to send the dog to the hospital for examination and symptomatic treatment.
