As a caregiver, you know the importance of safeguarding the health of your loved ones. In this context, your loved ones can also include your furry friends: your dogs. You’re aware that heartworm is a significant threat to your dog’s health, but do you know how dogs get heartworms? No worries, we have got you covered in the following sections:
Understanding Heartworm Disease
Heartworm disease is a serious and potentially fatal condition caused by parasitic worms living in the arteries of the lungs and occasionally in the hearts of dogs. The disease is transmitted through the bite of a mosquito infected with heartworm larvae.
The Lifecycle of Heartworms: From Mosquito to Dog
To fully understand how dogs get heartworms, let’s look at the lifecycle of heartworms:
- Adult Heartworms in Infected Dog: Adult heartworms living in an infected dog mate and produce offspring called microfilariae, which circulate in the infected dog’s bloodstream.
- Mosquito Bite: When a mosquito bites the infected dog, it picks up these microfilariae.
- Development in Mosquito: Over 10-14 days, these microfilariae mature into infective larvae within the mosquito.
- Transmission to Healthy Dog: When the infected mosquito bites another dog, it transmits the infective larvae to that dog.
- Maturation into Adult Heartworms: These larvae then mature into adult heartworms in about six months, completing the cycle.
Preventing Heartworm Disease
Preventing heartworm disease is much easier, safer, and cheaper than treating the disease. Here are some preventative measures:
- Regular heartworm testing.
- Administer heartworm prevention drugs as recommended by your vet.
- Attempt to minimize your dog’s exposure to mosquitoes.
Symptoms of Heartworm Disease
Knowing the symptoms of heartworm disease can help you detect the disease early and seek treatment. Here are some common symptoms:
- Mild persistent cough
- Reluctance to exercise
- Fatigue after moderate activity
- Decreased appetite
- Weight loss
Treatment for Heartworm Disease
Treatment for heartworm disease can be complex and costly. It often involves multiple steps:
- Stabilization of Dog: If the dog is very sick, it may need to be stabilized before treatment can begin.
- Administering Drugs: Drugs are given to kill adult heartworms and microfilariae.
- Post-Treatment Care: Strict rest is enforced after treatment to prevent complications.
