My dog got two partial Frontline doses. Is it safe or should I wash?

Pet's info: Dog | Miniature Poodle | Female | 12 lbs

There was not enough Frontline for a full dose so I used two. Both tubes seemed only half full. I’ve used them for years. Should I wash some off? Or just watch for a little ash?

Fortunately Frontline does not cause any symptoms of toxicity at 5 times the normal dose, so a double dose would not be a problem. I'm not entirely sure why there wouldn't be enough Frontline in a tube however unless it was open - perhaps you had some tubes that were for a smaller dog (the tube size is the same for different doses but there is less medication for smaller dogs). If the tube was open it may not be as effective and you may want to consider adding a different preventative. If you are not 100% sure you have the right dose size the safest thing to do would probably be to wash it off.
