Puppies can be given their first dose of topical flea treatment between 6 to 8 weeks of age, according to Adelaide Animal Hospital. Flea prevention treatment should be given once a month to prevent fleas and ticks from coming back.
Fleas and ticks are able to survive year-round, even if they do not have a host. They are worse during the warmer months and in warmer climates, but anytime fleas and ticks are spotted on a pet, the animal needs to be treated right away. Flea and tick products come in a wide variety of formulas, but a vet can offer the best advice for choosing the most appropriate one.
