If you haven’t read Part 1 of this article, “Heartworm Medication: Truths, Omissions and Profits,” please read it now unless you completely understand how and when heartworms are transmitted. Click the link at that article’s end to return here.  

A Heartworm Society news release states:  “By giving heartworm prevention every month, forgetful pet owners will have their pets protected when they need it most.”  But doesn’t that also mean they get it when they need it least? Or need it not at all? Are you a “forgetful” owner?

In this part of my heartworm series, we’ll discusses informed decision-making, and suggests ways, if you want them, to limit or eliminate heartworm drugs. I am a researcher and holistic health advocate, not a vet.  Please learn the facts then discuss with your vet the appropriate course given your dog’s location, lifestyle, travel schedule, health, climate and the time of year.  Expect an open-mind and respect from your vet, or find another vet.  Just as with vaccination, “one size fits all” is outdated, profit-driven, lazy medicine.

Take a look at the map above, courtesy of the  Heartworm Society.  Part 1 of this article demonstrated that transmission is heat and mosquito dependent.   As expected, dark areas of the map, which show the most heartworm cases per clinic, are found in the hot, humid Southeastern US, especially the Atlantic and Gulf coasts and Mississippi Delta.  

Don’t let the map scare you. If published seasonally, map colors would pale significantly during cool months. Also remember that you’re seeing generalities, not specifics.  A clinic near a rural pond will likely have many cases while an urban clinic 15 miles away may have a much lower incidence.  Maps are general.  Determine your own microclimate. Ask your vet how many cases of heartworm infection he/she treated in the past year.  Also ask if he/she treats all positive cases, or just those with advanced infestation. If the vet doesn’t keep detailed records, that should tell you something.

Conservative start/stop maps from heartworm researchers Drs. David Knight and James Lok (in “Seasonality of Heartworm Infections and Implications for Chemoprophylaxis”) show only two areas requiring year round heartworm meds: the southernmost areas of Florida and Texas.  Houston, New Orleans and similar areas are shown requiring meds for 9 months.  Other states range from 3-7 months. The Drs. wrote:  “For nearly 80% of the states, the potential for heartworm transmission is limited to 6 months or less.”  Here are start/stop maps for the US and California. Again, they are very conservative and very general. Do your own research and be specific.

The Heartworm Society warns that heartworm infectations are getting worse.  DVM Magazine, a magazine for vets, reports that recent results do show a rise in the number of positive cases per clinic in 31 states. DMV reports: “The reasons likely are multifactorial, including increased heartworm testing, increased client base per clinic or even climate trends.”  

Does Year Round Medicating Bring Extra Protection?

Applying suncreen at night is useless. So is taking heartworm medication when climate conditions prevent transmission.  Only a small percentage of climes permit year-round transmission. Everyone else is unnecessarily subsidizing drug companies and “preventatives” sellers and, more importantly, exposing their dog to unnecessary risks.

Two exceptions: 1) “Forgetful” and irresponsible pet parents who won’t begin the medication on time or build their dog’s natural immunity might want to medicate year round, although that means they have to remember to give meds every month.  2) If your dog contracts heartworms within a few years of beginning medication … and you can show you gave meds year round … and your dog had the required blood tests (2 or 3),  you may benefit a little financially because drug companies will pay for dog’s treatment.

 Are Heartworm Preventatives Safe?

You’ve seen those scary photos of worm-strangled hearts, right? Shouldn’t you give meds year round just in case? Isn’t safe better than sorry?

But is that harmless little pill or yummie medical “brownie” really safe?  No drug is completely free of risk and  adverse reactions.  I can find no long-term studies regarding cancer risks and organ damage for dogs receiving heartworm insecticides year round (or even for a few months). Such a study would be difficult to conduct and very expensive.  Who would fund such a study – or publish any negative findings?

One clue to the possibility of adverse reactions should be label warnings: call your doctor immediately if ingested; keep away from children; wash your hands immediately after use…. How can medication be good for dogs but so dangerous for you?

Another question: is your dog healthy enough for these medications? The “Heartworm Prevention” page of the American Animal Hospital Association states: “Healthy kidneys and normal liver functions are essential in metabolizing most medications.”  Many dogs, including my Jiggy, do not have healthy organ function. I wonder how many unhealthy animals are nevertheless on meds?  

Adverse Reactions to Heartworm Medications

With any drug, study FDA and manufacturer information before medicating.

These adverse reactions have been reported to the FDA by manufacturers.  Read more »

Heartworms are Spread by Mosquitoes. Heartworm Meds are Spread by Fear.

It’s getting warmer outside — time for sellers of heartworm medications to start scaring you to death.Television and print ads, which used to push meds only during warm summer months, now urge you to keep your dog on medication year round. The question is: why the change?

Drs. David Knight and James Lok of the University of Pennsylvania School of Veterinary Medicine, addressing recommendations for year round meds, warned:  “The practice of some veterinarians to continuously prescribe monthly chemoprophylaxis exaggerates the actual risk of heartworm transmission in most parts of the country and unnecessarily increases the cost of protection to their clients.”

So, is the change to year round meds all about money? Or is there more to this story?

Heartworm “prevention” is a major health decision for pet parents and multi-billion dollar Big Business for drug companies, veterinarians, testing laboratories and on-line sellers of medication. When health intersects money, there’s a lot of room for conflict of interest. Only by understanding the business aspects and the truth about heartworm transmission can you make an informed decision about if, how and when to protect your dog with commercial products.

While everyone agrees that heartworm infestations can be life-threatening, infestation is far from inevitable nor is it the immutable death sentence advertisers would have you believe. (Otherwise, all dogs and cats not on meds would die of infestation. But they don’t.)

Every holistic vet I’ve consulted had concerns about the long-term safety of heartworm medications. Well-known vet, author and columnist Martin Goldstein wrote in his wonderful book The Nature of Animal Healing that he sees heartworms as less epidemic than the “disease-causing toxicity” of heartworm medicine.

Dr. Jeff Levy, vet and homeopath, concluded “that it was not the heartworms that caused disease, but the other factors that damaged the dogs’ health to the point that they could no longer compensate for an otherwise tolerable parasite load.” Those factors include, “… being vaccinated yearly, eating commercial dog food, and getting suppressive drug treatment for other symptoms….”

Heartworm meds do not, by the way, prevent heartworms. They are poisons that kill heartworm larvae (called microfilariae) contracted during the previous 30-45 days (and maybe longer due to what is call the Reach Back Effect).

The heartworm industry authority, The American Heartworm Society (and their cat heartworm site) offers a wealth of information. Their website is a public service but also a marketing tool aimed at buyers and resellers of heartworm meds. Sponsors of this website are a Who’s Who of drug companies. Fort Dodge Animal Health (Wyeth), Merial and Pfizer are “Platinum Sponsors.” Bayer merits Silver. Novartis, Schering-Plough, Virbac and Eli Lilly get Bronze. Most of these companies have sales reps that regularly call on vets and show them how to sell you heartworm meds. With any purchase of any drug, we recommend you ask for information regarding possible adverse effects, the necessity for taking this drug and available alternatives.

How Heartworms Infect Dogs: It’s Not Easy!

Well, now that we’ve looked behind the scenes of the heartworm industry, let’s take a look at how the heartworms themselves (called Dirofilaria immitis) do business. Seven steps must be completed to give your dog a dangerous heartworm infestation:

Despite the huge tumor on his mouth, this sweet dog was given 7 shots 4 weeks before this photo was taken. The tumor grew 10-15% after the shots."

Most knowledgeable vets agree that certain animals should NOT be vaccinated (absent proven, urgent need such as inevitable exposure to a life-threatening disease). These  include, but aren’t limited to, pets with autoimmune disease … pets undergoing chemo, radiation or surgery (even dental cleaning or neutering) … pets with autoimmune disease, cancer, severe allergies and skin diseases … pets fighting an illness or parasites … pets stressed from shipment or a move to a new home … malnourished pets … and dying housebound pets.  Assaulting the immune systems  of these animals with vaccination has been likened to throwing gas on a raging fire.

Vaccination is big business and an old habit.  Dogs and cats need an advocate with common sense (and a strong backbone) to stand up for their pets. That means you!

So why shouldn’t you vaccinate a sick, stressed or geriatric pet? For one thing, the pet may develop adverse reactions ranging from fever to seizures to autoimmune disease to anaphylactic shock  and even death. (Click this link  to see other possible adverse reactions.) Furthermore, shots administered to an unhealthy animal may fail to provide immunity while giving you the false security that your dog is protected.  On top of that, Read more »

As most of you know, I have for years been sounding the warning siren about the slow poisoning of dogs from pesticides, co-called “preventatives” and other toxic chemicals. If your e-mails are any indication, many of you are listening. But many of you aren’t. Veterinary waiting rooms continue to be filled with accidentally poisoned pets. Some of these pets don’t survive.

Okay, I’ve said it before and I’ll say it again: 46% of dogs and 39% of cats dying of disease will die of cancer. Pesticides are proven to increase your dog’s (or cats) chance of getting cancer.  A University of Pennsylvania vet school study showed topical insecticides (aka preventatives) “significantly increased” bladder cancer risk, especially in overweight dogs. Other studies have shown cancer risks from herbicides. Some products meant for pets can even increase the chance you and your children will become ill.

Snail, ant and rodent baits may also prove deadly, sometimes killing quickly, sometimes slowly. Don’t think it can’t happen to your pet. Read more »

The cost of vet care for 2008 is estimated at $10.9 billion, up almost a billion from last year. With the economy tanking, jobs disappearing and the stock market down, many of us are postponing or foregoing dog care because we can’t afford treatment. It’s time — past time! — to cut out those unnecessary products and services too many pet parents think are essential — but may actually be harmful. Here are some cost-saving ideas that will also make dogs healthier:

1. STOP VACCINATING UNNECESSARILY! No more vaccinating against diseases your dog is unlikely to catch and against diseases to which your dog is already immune. Not only is unnecessary vaccination a huge waste of time and money, the resulting adverse health consequences can ruin doggy health and cost you a fortune in vet bills down the line. Watch our video Vaccinating Dogs for suggestions, and read or reread “Rethinking Vaccination” in our book, Scared Poopless. Also, read our blog article on titer testing. (Click here.) This simple blood test is especially important to prevent over-vaccinating puppies.

2. FEED QUALITY FOOD. Read more »
