Dog Deworming Schedule Chart: Puppy to Adult (2026)

A useful dog deworming schedule is not one fixed dose repeated forever. The timing changes as a puppy grows, starts monthly parasite prevention, and reaches adulthood.

Practical age checkpoints

Age What to discuss with your veterinarian
About 2 weeks Starting a veterinarian-selected deworming product
4, 6 and 8 weeks Repeating treatment at the interval on the veterinary plan
2 to 6 months Moving toward monthly broad-spectrum parasite control
Adult dogs Year-round prevention and fecal testing based on exposure risk

Medication choice and dosage depend on weight, health, location and the parasites being targeted. A schedule is a preparation tool, not a prescription.

The free PupVax dog deworming schedule chart lays out the puppy-to-adult timeline and the questions to take to a veterinarian.
