yeah fotze, it is for your "dog".... right.... good try. That is what you name "it" now?
That is like saying "Doctor, my friend has this itch that won't go away..."
Edit, seriously fotze, quick action is important, otherwise they will spread throughout your house too. Fleas apparently drown relatively easily, so going down to the river for a while or giving your dog a long bath (preferably outdoors) would be a good first step. There are, of course, flea collars, sprays, combs etc, and a vet could give him/her a dip.
Cowperson might be able to provide wisdom on this as his worldly experience surely came across this problem before.
Second edit... he replied before I finished MY edit!! Quickest Cow on the 'net!!
