tho allergic to fleas is really allergic to poor food(science diet is terrible), the yearly occurrence of this thing of yours coincides with the highth of flea season up north.
my dog does this in april here in fla.
that reminds me to start washing her every day, then every other then every 3rd and so on with dr. bronners soap. at health food store or online.i get the eucyliptus.soap up and let dry then rinse.
actually you can brush your teeth with it too.
only soap i use on body.
i like the idea of soap you can put in your mouth. and gets you squeaky clean tho i don't overwash in winter to let vit d sink in.
