Doktor Doom - Dog Only Residual & Contact Flea Killer Spray
Description
TL;DR: Doktor Doom Dog Only Residual & Contact Flea Killer Spray is a 1 L dog-specific spray that kills fleas, ticks, and biting insects on contact and keeps working afterwards. It's formulated exclusively for canine use and made by a trusted Canadian brand.
Fleas and ticks don't wait for a convenient moment. This Doktor Doom spray gives dog owners a straightforward, dual-action option for flea and tick prevention for dogs in Canada, combining contact kill with residual coverage in a single 1 L bottle.
Because it's formulated specifically for dogs, you can apply it directly to your pet when used as directed — no guesswork about whether a general insect spray is appropriate for canine use.
