Mark from Tuscaloosa, Al writes
It is recommended that dogs maintained under conditions of constant exposure to worm infestation should have a follow-up fecal exam within 2 to 4 weeks after first treatment. The manufacturer suggests that, for maximum control and prevention of reinfestation, it is recommended that puppies be treated with Happy Jack Liqui-Vict 2X at 2, 3, 4, 6, 8, and 10 weeks of age. A single dose each time usually is sufficient and begins to work right away. Follow up with your vet in 2-4 weeks. Complete instructions can be found on the product label here.
