Prior to administration of SENTINEL SPECTRUM Chews, dogs should be tested for existing heartworm infections. Precautions: Treatment with fewer than 6 monthly doses after the last exposure to mosquitoes may not provide complete heartworm prevention (see EFFECTIVENESS). If it is suspected that any of the dose has 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. SENTINEL SPECTRUM Chews may be offered to the dog by hand or added to a small amount of dog food. To ensure adequate absorption, always administer SENTINEL SPECTRUM Chews to dogs immediately after or in conjunction with a normal meal.
