Recommended Deworming Schedule
Deworming schedules may vary depending on the climate where you live and the activity of your dog. The following schedule should be used as general guidance. Newly weaned pups (6 to 8 weeks of age) should be dewormed at 6, 8, 10 and 12 weeks of age. Dogs over six months of age should be dewormed at least twice each year. Each deworming requires 3 daily treatments.
Caution
This medication should not be used in animals allergic to it. Do not deworm a dog or puppy that is sick. Consult your Veterinarian for the diagnosis of the illness. It is also important to eliminate fleas on the pet and in the household and to not feed the pet rodents or uncooked meat or fish. To prevent reinfection, daily cleanup of stools is recommended.
