Before retiring, I headed up our city's animal control dept. and then owned two dog care businesses. To help my clients I did a lot of research on flea preventatives. I'll pass my findings along to you folks: My research revealed that some flea preventatives using Permethrin have been harmful to pets, resulting in skin burns/ irritations, illness, nerve damage and even death. After treating your pet, watch them closely for the first 24 hours for anything out of the ordinary. If you see lethargy, vomiting, drooling, shakes, inflammation or irritation of the skin, immediately wash the area where you applied the medication with Dawn dish soap (de-greaser cuts through the oils in the skin), and then immediately take your pet to the vet.
The preventatives that are usually
safe:
Advantage: treats fleas, but not ticks.
Frontline: kills fleas and ticks but has become less effective in our area. Frontline spray works better, but don’t spray too much or too often, to avoid overdose.
Frontline Plus: treats fleas, eggs & ticks.
Revolution: treats fleas, eggs, mites,
ticks & heartworms.
Comfortis: oral pill , treats fleas only.
Those that are
UNSAFE for some pets:
Hartz: known to harm some pets.
BioSpot Spot On: harms some pets.
K9 Advantix: known to harm some pets.
Additionally, never use IVERMECTIN, which is a heartworm preventative, on a Collie Dog as most have an adverse reaction.
Hope this helps protect some of our furry friends.
