Heartworm, fleas, ticks, parasites … the list of insects that pet owners must guard their dogs against can be an intimidating one.  Even worse, trying to find the proper Preventative Medications can result in a dizzying maze of online research, trying to find which product does what, and the differences between the vast array of available products.  To make the job of every pet parent easier with new puppy or kitten, below is a handy guide to a number of different preventatives.

Heartworm

Arguably the most important preventative medication for dogs, there are many formulations and brands available.  Some simply prevent heartworm, while others prevent fleas, ticks, and parasites as well.

Advocate

Advocate is a multi-purpose, topical medication that is applied monthly to a pet’s fur.  Not only does Advocate prevent heartworm, but it also can be used as a preventative for fleas, hookworm, roundworm, whipworm, mange mites, and lice.  However, Advocate does not guard against tapeworm or ticks.  The active ingredients in Advocate are imidacloprid and moxidectin.  Unlike many other flea medications, Advocate can be used on cats

Interceptor

Unike Advocate, Interceptor is an oral tablet administered to dogs monthly that is used to control heartworm as well as roundworm, hookworm, tapeworm, and whipworm.  However, Interceptor has no protection against fleas.

Sentinel Spect Blue

Also an oral tablet, Sentinel Spect Blue is an all-encompassing product that protects against heartworm, fleas, and all intestinal worms (including tapeworm).  Sentinel is safe for use around cats, but does not protect against ticks.

Fleas

For dogs unable to take heartworm medications, or for owners who prefer to use two different forms of flea and heartworm control, a number of preventatives are available which only target these external parasites.

Advantage

Advantage contains Imidacloprid, which is a highly effective insecticide for the killing of adult fleas and larvae.  Applied topically once a month, Advantage can kill existing fleas within 12 hours.  However, Advantage does not protect against any other parasites or insects.

Advantix

Made by the same manufacturer as Advantage, Advantix is also a bi-monthly topical treatment and has the same flea-killing capability, but with the added ingredient Permethrin, which repels ticks, mosquitoes, and sand flies as well.  However, Permethrin is highly toxic to cats.

Bravecto

Like Nexgard, Bravecto is also a chewable tablet that repels fleas and ticks.  Unlike Nexgard, Bravecto’s active ingredient is Fluraner, which can kill any insect living on skin or fur.  Also unlike Nexgard, Bravecto is administered once every three months, whereas Nexgard is administered monthly.

Capstar

Capstar is a unique flea treatment that is an oral table administered daily.  For use when an infestation is found, or as a preventative when sending your dog to a new environment (such as boarding), Capstar is great for eliminating flea infestations quickly, but does not have any protection against other parasites.
