Apply the Correct Dosage
Advantage II products are specially formulated and tested for dogs of certain weights. The full dose of the correct product needs to be administered on a monthly basis. The infestation may continue if the manufacturer’s instructions aren’t followed. Don’t under-dose or over-dose pets. Under-dosing commonly occurs when pet owners split treatments between different animals. Toxicity concerns can also lead to under-dosing.
Re-dosing Early
Do not apply more than one tube per treatment, even for larger dogs. Under normal conditions, one dose will last 4 weeks. However, in severe infestations, it may be necessary to retreat the dog earlier in order to attain control. In these situations, do not retreat more often than once every 7 days. Once flea control is established, return to the monthly re-treatment schedule.
