   Step 1: First, check the label for the product's minimum age and weight (many parasite products aren't safe for very young puppies), and ask your vet whether the pill can be hidden in food or split — some can't. Never give human medicine.

   Step 2: Pill: sit your puppy on a non-slip surface (ideally with a helper gently holding them from behind), place one hand over the muzzle and tilt the head up. Gently lower the jaw with the other hand. Be quick but gentle; if they get very upset or try to bite, stop and ask your vet to show you or suggest another option.

   Step 3: Place the pill as far back on the tongue as you can (don't drop it down the throat), close the mouth and stroke the throat until they lick their lips.

   Step 4: Spot-on: part the fur between the shoulder blades until you see skin (they can't lick there) and squeeze it onto the skin, not the fur, in one or more spots as the label says. If they struggle a lot or try to bite, stop and try later or ask your vet for help.

   Step 5: Treat, then wash your hands. Avoid touching the spot and don't bathe your puppy for as long as the label says. Never use a dog product on a cat.

   Step 6: If you have cats, keep them from licking or snuggling your puppy for as long as the label or your vet says (at least 72 hours for permethrin spot-ons) — some dog spot-ons are highly toxic to cats, even through contact.
