Deworming is a crucial part of pet health care, but many owners still struggle with timing and medication choices. As 2026 begins, veterinarians summarize a comprehensive deworming guide to help owners protect their furry friends scientifically and effectively.
Deworming Timing: Different Stages, Different Schedules

For puppies and kittens, internal deworming starts at 2 weeks old, then every 2 weeks until 3 months old, and monthly until 6 months old. After 6 months, adult pets can be dewormed internally every 3-6 months, while those eating raw food or going out frequently need monthly deworming. External deworming: monthly for most pets, shortened to 20 days in summer (peak parasite season) and extended appropriately in winter.
Medication Selection: Targeted Choice Is Key
Internal dewormers: Broad-spectrum options containing praziquantel or fenbendazole are recommended to cover roundworms, tapeworms and hookworms. External dewormers: Choose products based on common parasites in your area, such as those targeting fleas and ticks. Combined internal-external dewormers are suitable for busy owners, simplifying the care routine. Always select pet-specific medications and follow weight-based dosing to avoid toxicity.
Key Reminder
Pregnant and lactating pets need vet consultation before deworming. Regular deworming not only protects pets from malnutrition and skin diseases but also prevents zoonotic parasites from endangering family health. Avoid the myth that "indoor pets don’t need deworming"—parasite eggs can be brought home via shoes or clothes.
