How often should a dog be given external deworming?

A dog can be externally dewormed every 1-3 months, with the exact frequency based on the actual situation. If the dog has little fur or rarely goes out, the interval can be extended to every 2-3 months.

But if the dog often plays in grass, woods, or other parasite-rich places, raise the frequency. If the owner finds parasites on the dog, deworm it immediately to prevent the parasites from constantly taking the dog’s nutrition and causing malnutrition or internal metabolic disorders.
