How to deworm puppies? When you newly adopt or buy a small puppy, you may wonder when to start deworming? You might worry the puppy is too young and deworming might harm it, or if it’s older, you worry about worms in the stomach or fleas on the body. Let me talk to you about the most suitable time to deworm puppies.

       How to deworm puppies? Puppy deworming mainly includes internal deworming and external deworming. The first internal deworming is generally around 20 days old (between 3-6 weeks). The first external deworming is usually around one month old. Deworming is not better if done more frequently; it depends on specific conditions. Too frequent deworming can actually impact the puppy’s health.

       The parasites of dogs mainly include internal parasites and external parasites. Common internal parasites include: roundworms, hookworms, heartworms, tapeworms, etc.
Common external parasites include fleas, ticks, demodex mites (follicle mites), scabies mites (sarcoptic mites), ear mites, etc.
    For the first internal deworming, we choose before the first vaccination, usually around 3-6 weeks old (about 20-40 days). Start once a week and continue for a month. Then once a month; after 6 months old, if the dog is kept as a pet, once every three months is fine. After the dog becomes an adult, deworming once every six months is sufficient.
 

  Note: Many deworming medications have age restrictions. Deworming too early can affect the puppy’s health. If you notice the puppy's spirit, appetite, bowel movements (or find parasites in stool), or abnormal digestion, consider if it is time to deworm.

       For the first external deworming, we generally choose around one month old. However, there is no fixed schedule for how often to externally deworm the dog; it depends on the situation. Frequent external deworming can affect the dog’s health. For example, in spring—an ideal time for outdoor walks—if the owner takes the dog to rural areas, woods, or parks, after the dog has been running in the woods, it is advisable to do external deworming upon returning home. Of course, you can also use deworming collars when taking the dog out, which can effectively prevent infection by external parasites.
