hi, just wondering what could be going on with ella... she was covered for the first time ever with lots of fleas.. prob 20 or so! we've never had this problem & she's on the k-9advantix every month. i've never even bathed with flea shampoo or used flea spray. the advantix always seemed to work until now! i also gave her the capstar pill i believe it's called. now she's digging at her skin & scratching behind her ears & her neck, but when i check her there is not a flea anywhere to be seen. could this be an allergy to the flea shampoo & spray? also this is a crazy question, but will dogs always have at least a flea or 2 on them? thanks for your help... this has been the best informative website ever! esp for a worry wart like me
