first: if you diside to eat a orange save the peels! im an animal expert and reading vet books gives me lots of info,like i found out most flea meds. sold are made with citris because citris is poisonous to fleas.
im gonna be honnest you need to do this after you give your dog a bath because there is no way you can get all the fleas without a bath first.rub the peels into your dogs fur all over. it will also leave a fresh scent.
