Flea Medicine

Capstar flea medicine is the best I've ever seen and one that works like it says it does after a half an hour my dog stopped itching completely very nice for not having to bring him to the vet to get flea medicine which cost out the butt and no vet visit which cost even more!!!

This stuff really works we use it once a month, the morning after we apply the liquid medicine leave them outside for 1-2hrs bc the fleas will be jumping off and you don't want them jumping off inside the house. It won't last but that's what the liquid is for. Do this once monthly and we're not seeing much activity at all we use the monthly liquid treatment from Walmart for small dogs as all our dogs are under 5lbs

This stuff works great kills fleas within 30 minutes to an hour, but it will not protect against reinfestation. Pet needs to be treated to control reinfestation and house and yard needs to be treated also.
