What are heartworms?

Heartworm disease is a very serious, potentially life-threatening illness. Heartworms can be transmitted in a number of ways, especially through mosquito bites. Mosquitoes carry heartworms from infected animals to your pet, spreading baby worms that will mature into an infective larvae stage within 10 to 14 days. Infective larvae enter new hosts through the open wound of a mosquito bite, growing over the course of 6 months into adults. They can live for as long as 5 to 7 years inside dogs. Heartworms are a foot long, and they take up residence in your pet’s blood vessels, lungs, and heart. They can cause heart failure, severe lung disease, and organ damage. Once heartworms find their way into your dog’s body, they reproduce. Dogs have been known to harbor hundreds of worms at one time. While heartworms can sometimes be eradicated, the damage they leave behind lasts forever. The damage will permanently affect your dog’s quality of life. Heartworm in dogs can prove fatal.

When your pet is newly infected with heartworms, they may not show any symptoms. As the infection progresses, the symptoms of heartworm in dogs will likely appear or worsen. The most common symptoms of heartworm disease are mild, persistent coughing, decreased appetite, fatigue after moderate activity, reluctance to exercise, vomiting, and weight loss. Your pet could show other symptoms as well. Heartworms are incredibly difficult to treat, so the best course of action is prevention with heartworm medication. Heartworm medicine for dogs is an important but easy way to keep your beloved pet safe.

How can I prevent my dog from heartworm disease?

You may wonder, why do you need a prescription for heartworm medicine? The answer is simple. Heartworm medicine treatment should only be initiated when your dog has tested negative for heartworms. If they are already infected, they should be treated for existing heartworms before they begin preventative medication. While it might be frustrating that you cannot obtain heartworm medicine without a vet, it is important to the health of your dog. Over the counter heartworm medicine would not be safe for your dog. Luckily, heartworm tests are easy, fast, and affordable. Once your dog tests negative for heartworm disease, you can have a discussion with your veterinarian about the best heartworm medicine options for your pet.

Heartworm pills for dogs are a popular, easily administered way to protect your dog from heartworms. Heartworm prevention for dogs should be discussed with your veterinarian so you can decide on the best choice for your dog’s individual needs.
