A transdermal liquid used monthly. Application is on the skin between the shoulder blades. Prevents heartworm, inactivates flea eggs, and kills adult fleas, ear mites, and mange. Also controls roundworms and ticks. Pet can be bathed 2 hours after application is applied. This product can be given to heartworm infected dogs and cats but is not a cure, this is why we strongly recommend a heartworm test if pet was not on a prevention last year.
This is a once a month chewable pill that kills roundworms, hookworms, whipworms and heartworms. The flea control portion is a hormone that renders the fleas sterile. It does not actually kill the adult fleas. If you run into an adult flea problem. you will not get the population explosion of fleas in your house because the sentinel is on board, but you may want to get rid of the adult fleas on your pet by using either comfortis or capstar. Sentinel must be given with a full meal.
