What to do if a puppy eats its own faeces

Puppies eat their own faeces in two ways: a disease manifestation, sometimes the dog is deficient in trace elements and the external supply is not sufficient, the puppy will eat its own faeces to achieve reabsorption, so this is the time to give the dog a timely trace element supplement. The other is a bad habit, which requires training by a professional dog trainer to correct the bad behaviour.
