Parasites not only affect a pet’s health but can also be transmitted to family members. Regular deworming and flea prevention are essential responsibilities for pet owners.


Internal Parasites: Roundworms, Hookworms, Whipworms, and Protozoa
Internal parasites can cause diarrhea, vomiting, weight loss, and weakness. Puppies and kittens are particularly susceptible to infection. The deworming guide for dogs states that puppies should be dewormed immediately after they are acquired, and then every 2–3 weeks until 6 months of age, followed by once a month. Adult dogs are generally recommended to be dewormed every 3–6 months, with the specific frequency determined by the veterinarian based on their living environment and risk assessment.


External Parasites: Fleas, Ticks, and Mites
Fleas and ticks can cause skin itching, allergies, and anemia, and can even transmit other diseases. Mites can cause severe itching and hair loss. Preventive measures include using monthly topical drops or oral preventive medications, regularly cleaning the environment, and brushing the pet’s coat.


Deworming Schedule and Recommendations
Puppies and Kittens: Start deworming at 2–3 weeks of age, then every 2–3 weeks until 6 months old.
Adult Dogs and Cats: Generally recommended to be dewormed every 3–6 months; those living in high-risk environments can be dewormed monthly.
Exotic Pets (Rabbits, Chinchillas, Guinea Pigs, etc.): Deworming frequency should be determined by the veterinarian based on a fecal examination and the specific species.
Pregnant and Lactating Animals: Some deworming medications can be harmful to fetuses or young, and must be used under a veterinarian’s supervision.


Identifying Symptoms and When to Seek Medical Attention
Signs of parasitic infection include: loss of appetite, abdominal bloating, weight loss, rough coat, vomiting, diarrhea, or visible parasites in the feces. Skin parasites manifest as itching, hair loss, and red, swollen skin. If these symptoms appear, seek medical attention immediately.


Clinic Process
During a clinic visit, the veterinarian will ask about the pet’s living environment, frequency of outings, diet, and past deworming history. After a physical examination, tests such as a fecal analysis, skin scraping, and blood tests will be conducted to identify the type of parasite and prescribe the appropriate medication.


Preventive Measures and Home Environment Management
Regular Deworming: Administer medication according to the veterinarian’s recommended schedule.
Clean Environment: Vacuum frequently and wash pet beds and toys to reduce fleas and their eggs.
Avoid Contact with Wildlife or Feces: When walking, prevent dogs and cats from sniffing other animals’ waste.
Balanced Diet: A strong constitution can boost immunity and reduce parasitic infections.
Multi-Pet Household Management: New pets should be isolated and dewormed before interacting with other pets.
