Prevention
The first fall seasons we lived in our little clearing in
the woods, hunting dogs would wander through, nose to the ground. I’d dutifully
shoo them away, although they never seemed interested in the livestock or even
my own dogs. I had no desire to touch them, as ticks in every stage of
engorgement dripped off their ears and other tender parts of their lean, weary
bodies.
Many of us remember the days when we had to “dip” our dogs.
It was messy, toxic, it stunk, and we could only imagine what we were doing to
our pets while fleas and maybe ticks dropped off. Now we have topicals that are
easy to apply.
The Companion Animal Parasite Council (CAPC) is an
independent council composed of veterinarians and health care professionals
that establishes guidelines for control of parasites. Here are some of their
recommendations for tick prevention:
remove habitat that ticks live in such as tall grass,
keep weeds down, remove brush piles,
select plants that do not attract deer.
If you are interested in the chemicals that they suggest to
spray in the environment, you’ll have to go to their website. We’re organic
here at Millknock and I think it makes a difference. We’ve not had fleas in the
17 years we’ve lived here and I attribute it in part to the fact that we have
not made bionic “super resistant fleas” due to not spraying or using pesticides
to eliminate them. However, I realize that some parts of the country have
severe flea problems they must deal with.
For treatment of ticks, CAPC recommends:
Remove them manually
Regular application of acaricides. The acaracides with the
greatest efficacy are: amitraz (available in a spot-on formulation and an
impregnated collar), fipronil (available in a spot-on formulation and an
impregnated collar), and permethrin (available in a spot-on formulation and an
impregnated collar). These three may help prevent tick attachment and can cause
tick death within 24 to 48 hours.
Certain permethrin formulations seem to have a repellent
like-activity that you can use on your clothing or material. Amitraz, fipronil,
and permethrin spot on formulas can be safely used on dogs, but only fipronil
is approved for cats.
Selamectin kills just two kinds of ticks on dogs and has a
slower speed of kill, so may not be as effective in removing ticks in the 24-48
hour span.
The Preventic collar is considered the most effective
treatment against ticks, but has no effect on fleas. It contains Amitraz, a
powerful chemical, and you need to heed the warnings that accompany the collar;
do not allow your pet to ingest any part of the collar. If you have multiple
dogs, and there is risk of mouthing the collar in play, it may not be the
preventative choice for your dogs. It lasts for 3 months and is the least
expensive tick treatment.
Frontline is probably the most recommended tick and flea
treatment by veterinarians. It contains fipronil. Frontline does not enter the
bloodstream, but travels along the skin and settles in the sebaceous-oil-glands
of the dog. As the tick crawls along fipronil attacks the nervous system of the
tick and paralyzes before it can bite the dog and pass infection. Application every 30 days is best, as
you risk making the ticks more resistant to the fipronil if you try to extend
the time. One recommendation is to not follow the directions for applying
Frontline in one spot, but spread it down the back in increments, against the
skin, which will shorten the amount of time (up to 48 hours) that it takes to
cover your dog. (and it won’t drip down the shoulders as I’ve seen it do on my
dogs)
K9Advantix is another top spot whose ingredients are
permethrin for ticks and imidocloprid for fleas. It works the same way as
Frontline.
Oral and injectable treatments, in my opinion, are not
recommended. They enter the bloodstream and do not work until after the tick bites the dog. I think the least invasive
approach to our dogs' health is the best one. These other alternatives add tick
prevention as a secondary benefit.
If you want to read more about tick diseases in dogs, I
found a wonderful website devoted entirely to the subject. It is fairly well
established that there are many tick-born diseases that don’t even have a name
yet. Research indicates ticks could be responsible for diseases not previously
attributed to them. Tick born disease is also not always diagnosed correctly.
Your vet can do an in-house Snap test to test for Lymme, Erlichiosis,
Anaplasmosis and Heartworm. If
indicated or there is a question of results, you can do a Quantitative C6 test.
Elizabeth Kolbert, in her fascinating article titled The Fifth Extinction? describes five big extinctions in our earth’s history. There
was once a mass extinction of brachiopods (they look like clams) and most of
the marine animals and today there is evidence of another mass extinction of
creatures such as frogs and bats. Frogs and bats contribute to the
environmental equilibrium, no one has found a “reason” for ticks. My question
is why can’t we have a mass extinction of ticks!
