Puppies should be dewormed when they are about 2 months old. It is recommended to perform external deworming first, and then internal deworming the next day to prevent excessive deposition of drugs in the puppy's body. Since puppies are lighter at this stage, and excessive amounts of anthelmintics can cause poisoning in puppies, it is recommended to choose safer anthelmintics and pay attention to the dosage.

Puppy owners need to know what deworming drugs are available for puppies and whether they are suitable for puppies. Because puppy deworming is based on weight and physical condition, so owners should choose carefully. A good deworming medicine can drive away parasites in the intestines and reduce the adverse reactions of puppies after deworming.

When pets take deworming medicine, when the medicine takes effect, each pet has a different constitution and will react differently. Some pets have no special reactions, but some may experience symptoms such as mental distress, diarrhea, vomiting, etc. These are also normal phenomena and pet owners do not need to worry too much. Owners can fast for 4-6 hours and take probiotics to reduce gastrointestinal burden.
