Heartworm Prevention for Dogs with Food Allergies


Did you understand that there are unflavored heartworm preventative chews out there, in addition to different types of preventatives? I didn’t both, till just lately. 

Pixel, my sister’s canine, was simply identified with a gastrointestinal illness that was inflicting irritation of her intestinal tract and malabsorption of meals. Fortunately, this situation was rapidly resolved by altering Pixel’s weight loss program to a novel protein and eliminating any meals with beef, pork, or rooster and she or he is now thriving. Then it turned time to manage her month-to-month chewable heartworm preventative. My sister hesitated: The chewable preventative treatment that she ordinarily used to guard Pixel was flavored with rooster, which Pixel couldn’t have. Fortunately, there are options, and Pixel’s veterinarian was glad to alter Pixel’s prescription to considered one of these.

Heartworm disease is a critical and probably deadly situation brought on by Dirofilaria immitis, a parasitic roundworm that’s transmitted to canines by the chew of a mosquito. Unfortunately, canines are pure hosts for the parasite, and as soon as it infects a canine’s physique, the larvae mature into adults, mate and reproduce, with the grownup types of the heartworm residing within the coronary heart, lungs, and related blood vessels. Heartworm illness may cause lasting injury to a canine’s physique and have a long run impact on well being and high quality of life. Heartworm illness has been identified in all 50 states; threat ranges for contracting the illness range and are troublesome to evaluate. Accordingly, prevention is often crucial in most areas. Heartworm drugs don’t truly forestall the transmission of the heartworm, however quite they act to destroy the larval phases of the parasite, stopping the event of the larvae into grownup heartworms. 

Prevention of heartworm illness is often achieved by the month-to-month oral administration of a flavored chew, which is very efficient when administered appropriately. Most oral heartworm preventives, nonetheless, include a protein-based part for flavoring, often pork, soy, beef, or rooster, of their formulation. Because many canines endure from meals allergy symptoms and sensitivities or are present process meals elimination trials (and flavorings can intervene with and have an effect on the success of the trial), heartworm prevention in these circumstances ought to be modified to a non-flavored oral method or topically utilized product. 

The month-to-month heartworm preventive HEARTGARD® (ivermectin) is obtainable in an unflavored pill type and doesn’t embody any meals substances that will set off an allergic response. A topical (utilized externally to the physique) heartworm preventative, akin to Advantage Multi, Revolution, or Selarid, is an alternative choice, particularly as this kind fully bypasses the gastrointestinal tract. 

There is a 3rd choice: ProHeart 6 and ProHeart 12 take the type of sustained launched injections of moxidectin (this ingredient can also be out there as a topical) and supply safety from heartworm an infection for six months and twelve months respectively. Its use within the U.S., nonetheless, nonetheless attracts controversy over considerations concerning antagonistic results (ProHeart 6 was taken off the market in 2004 due to security considerations, however it was reformulated and returned in 2008; ProHeart 12 was accepted for the primary time by the FDA to be used within the U.S. in July 2019). In different international locations, each merchandise stay in the marketplace and are in use.

As all the time, seek the advice of together with your veterinarian about your canine’s prescription heartworm preventative.
