Deworming tablet for dogs: when and how often?

The short answer

Puppy deworming tablet: 2, 4, 6, 8 weeks old, then monthly till 6 months.

Adult dog walking outside: deworm every 3 months. Vet picks tablet and dose.

Adult dogs with a different schedule

  • Strictly indoor dog: deworm less often, or stool test first
  • Eats raw meat or scavenges: tapeworm tablet 4+ times yearly

About deworming tablets

  • Routine tablets target roundworm, hookworm, whipworm, tapeworm
  • Not every tablet covers tapeworm; ask what yours covers
  • Flea tapeworm comes back unless dog's fleas are treated

Deworming mistakes to avoid
