sometimes brewers yeast tablets help keep fleas off of dogs, supposed to make their bood taste bad. mine with eat them willingly. when we came home to flea infested carpet, i sat down on the carpet with white socks on (catch them when they jump on them 🙂 – have a little bowl of water with a dash of dish soap handy to drown them in.
i sat there and picked all the fleas off my dog i could see ( they stick to your fingers dampened in the soapy water, then i thoroughly vacuumed. had to pic off more for a few days –but i did get rid of them!
