Sixty seconds to applied
The whole job is one tube and one spot the tongue can't reach. Snap the tube open, part the fur between the shoulder blades until skin shows, and squeeze the dose directly onto the skin — fur-level application just perfumes the coat.
Bigger bands split the dose along the back at the label's marked points, still always on skin, always where a twisting neck can't lick. Don't rub it in; it spreads itself.
Then the two quiet rules: no petting the spot until it's dry, and no baths or swimming for 24 hours — after that, the waterproofing holds through rain, lakes and shampoo for the rest of the month.
