Every year, veterinarians brace for a disease that has plagued our pets for decades. Yet this disease is easily preventable using affordable and safe medications. Occurrences of Heartworms in both dogs and cats persist to escalate and the expenditure to treat (if recognized soon enough) is actually far greater that the expense to prevent. Consequently, how will you provide protection to your furry friend from the lethal repercussions of this now widespread parasite?
Flash back to 150 years ago when a scientist first identified the heartworm parasite in a dog. Then the parasite evolved and was then diagnosed in our cats 80 years ago. Even though heartworm prevention is available for both dogs and cats you would reckon that we would experience a reduction in the amount of cases, nonetheless each year thousands and thousands of dogs and cats are diagnosed and all too often die too soon from this dreaded parasite. Several researchers estimate that in North America alone, cases of heartworms in our pets may actually be in the millions.
The disease brought on by this heartworm residing inside your pet’s heart is devastating. Your pet can be infected with the sole bite of only one mosquito. The worm will then migrate through your pet’s entire body eventually taking up residence in your pet’s heart chamber and the blood vessels leading to the lungs. This leads to your pet’s heart needing to pump harder to circulate the blood through his tiny body. The consequences on the lungs is even more severe with many pets gasping for breath as the lungs fill with fluid and tiny blood clots clog the vessels. Early symptoms may include coughing and exercise intolerance that some owners just attribute to the dog being lazy. More often than not, warning signs do not show up until the disease is well advanced and the dog is being affected by heart failure, fluid accumulation in the lungs and abdomen which often can ultimately result in death.
In cats, it only takes one heartworm to trigger damage. The early signs are asthma like symptoms and occasionally vomiting that the owners may attribute to hairballs. Whenever that heartworm lodges in the lungs, it can lead to a sudden death of the cat.
Treatment for heartworms is expensive starting from $500 for the smaller dogs, to upwards of $1500 for the bigger breeds. Complicated heartworm disease with heart failure is much more expensive and oftentimes there is only a 10% chance of recovery in the severely afflicted pets. As of yet, there is no treatment for cat heartworm disease, just supportive care.
Incredibly, veterinarians do have a remedy for this crisis. Safe, effective heartworm preventatives are available in a number of easy to use applications. What is even more amazing is that the expense of a lifetime of prevention for many pets is considerably less that a one-time treatment for the disease. And so, why do pets continue to suffer and die from such a preventable sickness?
With all internet beliefs, two radical hypotheses propose that either the heartworm medications are failing or that the parasites are developing a resistance to the medications. Although conspiracy theorists love these types of thoughts, medical proof for either theory is absent. Heartworm preventives possess a failure rate of less than 1 in 1 million doses. Furthermore, the intricate life cycle of the heartworm does not lend itself to creating a natural resistance to the medications. The truth likely lies in the remembrance of the owner to dispense the dose in a monthly manner and the climate.
Increasing temperatures in our climate has resulted in a lengthier mosquito season and a bigger potential for transmission to our pets. Here in Houston, our mosquito season is all year round. Some cities are presently experiencing significantly more mosquitoes in previously mosquito-free areas. Irrigation of dry areas and expanded plantings of trees in certain locations can certainly help to increase mosquito population. With a larger number of mosquitoes, there is a higher chance of transmission of heartworm disease.
When all of the facts are evaluated, the most obvious reason for our failure to control this fatal parasite falls on the humans themselves. We simply do not supply the preventive as we should. It could be attributable to forgetfulness, or perhaps one spouse assumed the other one gave it or it could be as a consequence of overall economy plus the financial constraints imposed on the family unit. Regardless of the reason may very well be, it can trigger serious implications for the sake of our pets.
Luckily, as pet owners, you do have powerful allies to help you fight the war against heartworms. With the help of your veterinarian, you can choose the best heartworm medication for your pet and your budget. Oral medications, like Heartgard, Sentinel, and Iverhart are available. In addition there are topical medications for example Advantage-Multi and Revolution that are formulated to also safeguard your pet from both heartworms and fleas. Proheart 6 is also available as a long lasting injection. The prevention of this disease rests solely on the pet’s owners to make certain the pet will get the prevention prior to the pet might be exposed to the parasite. That means that the prevention must get started in puppy-hood and be given each month, all year long.
You should not spend your time attempting to find “natural” or organic ways to prevent heartworms; they simply do not exist. Some people believe they can formulate ivermectin to offer to their pets, but incorrect dilution and storage can result in overdosing or underdosing. Follow recommendations by your veterinarian and the American Heartworm Society (www.heartwormsociety.org) Your pet is depending on you and prevention is more effective and cheaper than the treatment.
