Sentinel Spectrum may be administered year-round without interruption. Heartworm Prevention: Sentinel Spectrum should be administered at monthly intervals beginning within 1 month of the dog’s first seasonal exposure to mosquitoes and continuing until at least 6 months after the dog’s last seasonal exposure.

If it is suspected that any of the doses have been lost, redosing is recommended. Care should be taken that the dog consumes the complete dose, and treated animals should be observed a few minutes after administration to ensure that no part of the dose is lost or rejected. Chewables may be broken into pieces and fed to dogs that normally swallow treats whole. The chewables should be administered in a manner that encourages the dog to chew, rather than to swallow without chewing. To ensure adequate absorption, always administer immediately after or in conjunction with a normal meal.

Sentinel Flavor Tabs are given orally, once a month, at the recommended minimum dosage of 0.23 mg/lb (0.5 mg/kg) milbemycin oxime and 4.55 mg/lb (10mg/kg) lufenuron.
