Heartworm Prevention month

For those of you who may not be aware, Dr. Burrows, who lives in the Tanque Verde Valley got West Nile last fall. It took a bit of chasing to diagnose it, and when they finally did, all they could tell her to do was wait it out. Luckily for Dr. Burrows other than feeling pretty punky for a few weeks and having a bizarre tingling in her fingers that lingered for a month or so, the symptoms were very mild.

Which brings us to heartworms; heartworms do not affect people or they would be far more frightening than West Nile. They affect cats and dogs, and as the name suggests these worms migrate and live out their lives in the arteries around the heart.

What links these two diseases is the mosquito. Mosquitos account for more human deaths worldwide than any other animal. Arizona, with its dry climate is home to 46 varieties of mosquito according to the Arizona Department of Health. Mosquitos, the things that we, as Arizonans, take great pains to claim that we do not have are very much a part of our world. And as Dr. Burrows shows, not only do we have them, but they are carrying dangerous illnesses. (and yes, she picked up West Nile here)

No one wants to see their pets get sick, and every decision that we as pet owners take is a part of a balancing act between cost (not neccessarily financial) and benefits. We elect to put our dogs on tick prevention in the off chance that they may come into contact with a tick carrying a debilitating or fatal disease, or we deem the annoyance of tick products, their cost, their unsavory feel in our pet's coat, their toxicity no matter how small, too high and use them sparingly during travel.

This is a cost/benefit analysis and we, as pet owners do it every day. However, the only way this equation works is through education.

So, what we want pet owners in Southern Arizona to know, and what we strive to reinforce every day, is that the tightrope between cost and benefit that we have been walking for some time when it comes to heartworms has swung and that the danger of this disease, its rising prevalence in our coyote population, the increased interstate travel of your neighbors (and yourself) have all made the risk of doing nothing too high.

No one, not even veterinarians talked about heartworms in Southern Arizona even 15 years ago. But part of the belief that something isn't here is not looking for it. It was the advent of easier heartworm tests that saw an upswing in positives across Pima County. After Katrina and the dispersal of heartworm positive Katrina dogs into area shelters, veterinarians who hadn't already, felt a need to step up monitoring and prevention efforts.

Sadly, the numbers indicate that at least two or three of the dogs in our practice are, at this very moment, positive for heartworm. Perhaps they have no symptoms, or they have an occasional cough, or they are slightly more lethargic and the owners have put it off on age. We want to find these pets and help them feel better, and more importantly, we want them to stop carrying this deadly parasite in their blood.

The hearts represent all of the dogs who have come in so far this March who are protected against heartworms

We urge you, if you haven't already, to come in, have a heartworm test done and put your dogs on heartworm prevention.

Heartworm disease is devastating. It is expensive and awful to treat, while being largely inexpensive (around a $120 a year for a 100# dog) to prevent. The prevention that we use, Heartgard Plus also prevents against roundworms and hookworms.
