MedicationsMy French Bulldog has fleas. Can I give him Comfortis for treatment?
Legally, we are unable to recommend this in the absence of a patient-veterinarian-client relationship and physical exam. You should contact your veterinarian. If your vet gives the okay, treat all your pets for at least 3 consecutive months, preferably year round. Your vet can dispense Capstar which will rapidly kill any adult fleas on your pets to get a jump on treatment. You will also need to treat the environment. This will include vacuuming everywhere the dogs have been, washing all bedding and using an area treatment, such as Knockout ES, to prevent reinfestation.
