Frontline plus is still the gold standard, as far as I'm concerned. Some of the newer ingestible flea/tick products are not safe for Mals or Dutchies.
As far as the family goes, and for the foxtails. Try to find Avon skin so soft. Mix half and half with water, shake well to mix, and spray on clothing, dogs, etc. it works well as a repellent, and has the added bonus of making foxtails easier to comb, pick, or brush out. In a pinch, for the foxtails, just mineral oil in a spray bottle will help, but the avon product takes care of a couple aspects of your new environment.
