For Large Dogs 34 to 66 lbs.
Spot-On BugOff for Dogs™ is a triple action formula that kills adult fleas and ticks, prevents eggs and larvae from growing to adulthood and prevents new pests from getting on your dog. Spot-On BugOff for Dogs™ contains two active ingredients: Permethrin and Pyriproxyfen. Permethrin is an insecticide/matricide that kills and repels adult fleas, lice, and ticks. When applied, it disperses
in the pet’s natural skin oils into the sebum, protecting your dog from pests. Pyriproxyfen (also called Nylar) is an insect growth regulator (or IGR) that is particularly effective at preventing eggs and larvae from developing into infection spreading adults.
