Dogs are prone to one of the most serious and, potentially, life-threatening conditions, namely heartworm disease. This is a parasitic disease (Dirofilaria immitis) transmitted by mosquito bite which leads to severe pulmonary disease, heart failure, and organ damage. Dogs need to be understood to have a holly about heartworm disease and catching make can mean life or death for their dog. In this article, we will talk about heartworm disease in dogs, the symptoms, the diagnosis, treatment options, and the prevention.
The parasite worms that cause heartworm disease live in the heart, lungs, and blood vessels of the infected dog. Mosquitoes are the vector of these worms and warmer more humid parts of the globe are more prone to outbreaks. One characteristic of dogs is the fact that they will contract the disease from the saliva of an infected mosquito when the latter bites their skin. These larvae over time grow into adult worms which cause severe complications in life.
However, the disease can affect dogs of all breeds and sizes. In fact, dogs are particularly dangerous because, in its early stages, dogs will not have any symptoms. The damage to the heart and lungs may already be severe when the infection is advanced. Advanced heartworm disease in dogs can be fatal if left untreated.
As a mosquito bites an infected animal, it ingests microscopic larvae called microfilariae, which initiate the life cycle of the heartworm. The larvae develop inside the mosquito and are subsequently bitten by a second dog and transmitted to them. The larvae mature over many months inside the new host and end up as foot-long worms that take up residence in the lungs and heart. Adult worms can live in a dog's body for many years, and the entire life cycle lasts about six to seven months.
The extent of the infection and the duration for which the dog has the infection may influence the signs of heartworm disease in dogs. Most dogs don't show signs in the initial stages. Nevertheless, the body of the dog starts showing signs of discomfort as the worms continue to grow and multiply.
Early heartworm disease in dogs is usually described by a decrease in exercise, lethargy, and a mild cough. Formerly energetic dogs can become tired easily after a short play or walk. Some dogs can also experience loss of appetite or weight loss.
Advanced heartworm disease in dogs can result in severe respiratory distress and cardiac failure as the infection advances. High worm-load dogs can cough incessantly, experience difficulty breathing, and pass out at times. Congestive heart failure, an illness involving fluid buildup within the belly, can result in swelling in some individuals.
Caval syndrome is a life-threatening complication that may develop in the most acute cases. This happens when a large number of worms clog the blood supply of the heart, leading to shock and sudden collapse. The outcome is often poor despite treatment for caval syndrome, which requires urgent surgical surgery.
Diagnosticians in veterinarian clinics use clinical examination, blood work, and imaging to determine heartworm disease in dogs. The antigen test, which seeks out proteins the adult female heartworms excrete, is the most prevalent. At least six months of infection will be identified with this test.
To search for immature worms in the blood, a microfilaria test might sometimes be performed. Other tests, such as a chest X-ray or ultrasound, might be recommended if a dog tests positive to assess the severity of the infection and select the best treatment plan.
Even if they are on preventive medication, all dogs are recommended to have a yearly test for heartworm disease. For dogs that have missed a preventative dose or have been bitten by mosquitoes in high-risk areas, a test is especially important. While they may start heartworm prevention without testing, puppies under seven months of age should be tested six months later to ensure that they are not infected.
Treatment of dog heartworm disease is a long and challenging process. Melarsomine, which kills adult heartworms, is administered multiple times as the main treatment. The drug is administered at a veterinary clinic and must be monitored closely because heartworm death can lead to blood vessel blockages and inflammation.
Dogs undergoing therapy must be kept calm and avoided from physically strenuous activities. This is because when the worms die, they decompose, and can lead to effects such as lung inflammation or blood clots. To prevent possibly lethal reactions, strict exercise restrictions must be observed for a few months.
Dogs can receive anti-inflammatory medication, antibiotics, and heart medications alongside the main treatment to manage symptoms and avoid complications. In severe cases, hospitalization may be required to provide supportive therapy and oxygen therapy.
Surgery to surgically excise worms from the lungs and heart might be needed for those with serious heartworm disease in dogs. Generally, this is only considered in severe cases when the worm burden is very heavy and standard therapies would not be effective.
Preventing heartworm disease in dogs is easier, safer, and cheaper than treating an infection. Monthly heartworm preventives effectively keep larvae from developing into full-grown worms and come as chewable tablets, topical solutions, or injectables.
Even in colder climates, year-round prophylaxis is highly recommended because mosquitoes may still be active during unexpected warm periods. Uniformity is also required because failure to administer doses of prophylactic medication may put a dog at risk.
The danger of heartworm disease also can be reduced by reducing exposure to mosquitoes. Danger of mosquito bites can be reduced by keeping dogs in doors when mosquitoes are most active, applying pet-safe repellents, and eliminating standing water near the home. Additional protection also can be provided by screening or mosquito netting in outdoor areas.
All breeds of dogs are vulnerable to heartworm infection, yet some are likely to be more impacted than others due to size or genetic factors. Even though big breeds such as Labrador Retrievers and Golden Retrievers might be more resistant to minor infestations compared to small breeds, if they are not treated, they too risk contracting severe disease.
Even with a minimal worm burden, small breeds like Chihuahuas and Toy Poodles can suffer greater lung and cardiac damage. Also, certain breeds are more likely to suffer the consequences of heartworm disease if they have underlying cardiac problems.
Heartworm disease is a preventable, serious but not curable, condition for which every dog owner should educate themself. Being able to understand what heartworm disease is in dogs and knowing the symptoms of heartworm disease in dogs is key to saving a dog’s life. By early detection through routine testing, and prompt treatment, complications can be prevented and the outcomes of infected dogs improved. The best approach with dog owners is prevention.
