Beaumont's Journey with heartworm

This is the first entry in what will be an on-going story following a sweet dog named Beaumont and his treatment for heartworm disease. Heartworm is easy to prevent. But, as you'll see below and over the coming months, it is hard to get rid of once infected.

Heartworm disease is typically spread when a dog is bitten by an infected mosquito. We may think our dry climate makes mosquitos less prevalent, but it’s a real risk in Colorado and the incidence of reported cases has been increasing.

Beaumont is a big, lovable puppy who was adopted from a Colorado dog rescue in January of this year by Kristin, one of our Customer Care specialists. He came from out of state and initially tested negative for heartworm in the test done by the rescue organization. The week after his adoption, Kristin brought Beaumont in for a wellness checkup and blood work at our hospital. Unfortunately, this time his heartworm test was positive. Though uncommon to test positive so quickly after testing negative, the rescue offered to pay for the cost of the heartworm treatment drug to ensure a successful adoption.

This meant an end to long walks and his goofy rambunctiousness for a while because restricting exercise is important for heartworm-positive dogs.

This also meant a beginning to heartworm treatment.

We begin the Nine (9) month treatment regime

Our initial goals of treatment were to make sure Beaumont was stable, and then to kill all immature and adult worms in his body.

Days 1-3, Diagnosis confirmation

First, we confirmed Beaumont's diagnosis with a more specific and specialized test that can detect even small pieces of heartworm skin floating in his blood. Heartworms must be at least seven months old before they can be diagnosed; likely explaining why he first tested negative after his rescue in December. 

Radiographs were then taken of his heart and lungs to look for damage to his vascular system (blood vessels). Thankfully, and because of early detection, Beaumont showed no signs of damage.

We started his 30-day antibiotic regime with Doxycycline to kill bacteria which live in the heartworms because these bacteria help the heartworms survive and reproduce, and cause increased inflammation. This drug helps him with any complications.

On day one Beaumont also started his monthly heartworm preventative.

Now, we have to slow him down! Beaumont is a high energy puppy but now must be kept confined and on strictly limited movement and activity for 6-to-8 weeks because exertion increases the rate at which the heartworms can damage the heart and lungs. When he's outside, it's only for short 5-10 minute bathroom breaks on leash, and then back inside for rest.

Day 60, drug Treatment begins

Two months after starting the preventive, Beaumont received a full physical and started treatment with Immiticide (also known as Melarsomine), the drug that will kill the adult heartworms. Because complications can occur, he stayed with us under the strict observation of a Veterinarian. After this he started Prednisone, a strong anti-inflammatory, when he went home. The Prednisone also helps decrease inflammation caused by the heartworms and their die-off because when adult worms die, they collapse and are pushed deeper into the smaller branches of the vessels that supply blood to the lungs. Continued rest is essential as exercise increases blood flow and further increases this risk. 

Tramadol and Gabapentin were prescribed to help manage Beaumont's pain as heartworm treatment is serious business.

That's where we are now with Beaumont's treatment. To learn more about what's ahead read below. This sweet dog and his family have quite a journey to come. We'll keep updating with each stage of Beaumont's Journey.


Day 90 & 91
One month after the first injection of Immiticide two injections of the drug must be given 24 hours apart. Once again, Beaumont will be in the hospital for observation.

Day 120
Exam and heartworm test for microfilaria (larva of the heartworm parasite).

Day 270, nine months after the beginning of Beaumont's journey
Treatment hopefully will be complete. We will perform a final heartworm test to confirm that all heartworms have been eliminated. We will also continue Beaumont on his monthly preventative at this time but if all goes well, he goes back to life as usual!
