Heartworm Prevention

As you may already know, heartworms are spread by mosquitoes, and it only takes one bite to infect a pet. Once infected, a heartworm can do severe damage to a pet’s heart, lungs, and blood vessels.

Sadly, many animals don’t show symptoms until the disease is advanced.  In dogs, signs of heartworm disease can range from coughing, fatigue, and weight loss to difficulty breathing and a swollen abdomen (caused by fluid accumulation from heart failure). Canine heartworm infection can also lead to a life-threatening complication called “caval syndrome” (a form of liver failure); without prompt surgical intervention, this condition usually causes death.

Although often thought to not be susceptible to heartworm infection, cats can indeed get heartworms. Cats can suffer from a syndrome referred to as heartworm-associated respiratory disease (HARD); the symptoms can be subtle and may mimic those of asthma or allergic bronchitis. Signs of respiratory distress, such as rapid or difficult breathing, wheezing, and panting, are common. Other symptoms include coughing, vomiting (typically unrelated to eating), and loss of appetite or weight. Heartworm infection is more difficult to diagnose in cats than it is in dogs.

While there is heartworm treatment available for canines, it is expensive and can be very hard on your pet. There is currently no treatment for cats.

As always, prevention of disease is best! Our veterinarians advise keeping your pet on heartworm preventive year-round. Be advised if your pet has not previously been on heartworm preventive, he or she will need a heartworm test before starting on one. Dogs currently on prevention will need a heartworm test once a year.

Please call us at 559-683-3313 to learn more or schedule your pet’s heartworm test.

Treatment for heartworm infection is far more expensive than prevention—and it can actually kill your dog. There is no approved treatment for cats. Some cats spontaneously rid themselves of the infection; others might not survive it. And even one or two adult heartworms in a cat can cause serious problems.

Fortunately, there’s an easy way to keep your dog or cat safe: by administering monthly heartworm preventives. Most heartworm medications also protect your pet against other parasites, such as roundworms, hookworms, whipworms, ear mites, fleas, and ticks. We can recommend the best regimen of prevention for your pet.
