Dogs should be dewormed. Fleas are a common external parasite infection in dogs. Commonly used clinical external deworming drugs include selamectin, moxidectin, etc. Pet owners can choose according to their own circumstances. However, attention should be paid to the differences in therapeutic dosage and preventive dosage and frequency during infection. Treatment needs to be applied every one to two weeks until the dog is completely healed, which usually takes two to three weeks.
