I've put the spray in dog's ears on the advice of a vet; we had an ear
problem we could not sort out.  She said "well it won't do any harm".
I've been told it is a practice done at ferret shows in France; the spray
is put on a cotton bud and wiped around the inside of the ferret's ears.
 
What is the problem with using Frontline in this way as it is not a
systemic product?
