O-Ren your poll doesn't give many choices.
I only voted to see results lol and did the middle one. I heard garlic wasn't good for dogs?
Please explain more, how old are your dogs? Is this a new thing? (the itchy scratchies). I use Advocate for fleas+ but don't like using chemicals but what else does one do? Sassafrass oil I hear is very potent, pennyroyal, lavendar.....
