Canine Heartworm Disease - A prevention guide.

In today’s world, we are often told by our veterinarians that dogs are susceptible to many illnesses, infections and diseases.
In this article, I will talk in details about the well known disease known as canine heartworms.
This disease is formally caused by the parasite Dirofilaria immitis which has taken the name heartworm over the years because it resides in the heart and major blood vessels of the dog.
For the majority of cases, dogs are infected through a mosquito bite. The mosquito releases heartworm larvae which enters the dog’s body, then grows to maturity and begins to reproduce in approximately six to seven months.
The signs that a dog is infected vary greatly on the amount of worms the dog is carrying. A dog that is carrying only but a few worms may not show any signs of illness, while a dog with a heavy load of worms may be lethargic, lose weight, cough during exercise or even pass out. Dogs with severe cases may even suffer from heart failure.
Heartworm disease can be cured by first poisoning the adult worms and to eliminate them from the dog’s system. The dog must be hospitalized during this process so that the veterinarian can monitor any complications that may occur, such as arteries being obstructed by the dead worms..
Three to six weeks later, the dog must be hospitalized again so that he can be treated to kill the baby worms which are still in his system. A dog is usually hospitalized for another eight hours.
Prevention is a far better treatment and it will save you lots of time, concerns and money.
There are a few types of medications available today for preventing heartworm disease. Some are only effective against heartworm disease, while others are also used to control hook worms, roundworms, whipworms, fleas and ticks.
It is important that you always consult your veterinarian before giving your dog any kind of medication. He is the most qualified person to guide you in the right direction.
Below is a short list of well known medications which are designed to prevent heartworm disease:
- Diethylcarbamazine (DEC) is given daily and protects only against heartworms.
- Heartguard Plus and Interceptor are given monthly and also protects against hook worms, roundworms and whipworms.
- Sentinel is a monthly tablet that protects against heartworms and fleas.
- Proheart is administered by a veterinarian and lasts up to six months.
- Revolution is applied to the skin and protects against heartworms, fleas, ear mites, mange and ticks.

I and other horse owners have found that guineas are an awesome way to keep the mosquito population down, along with various sprays and natural feed additives. Heartworm preventative is very important. Around here, this disease isn't the only scare. West Nile and a wide variety of other diseases are passed by mosquitoes, so we make sure to stay on top of the insect population.

1. Never give your dogs heartworm preventative when the temperature is below 64 degrees at some point during a 14 day period.
2. If you are going to give preventative during those times when the temperature is consistently above 64 degrees, only do it every 45 to 60 days. Studies have shown that is sufficient to kill the heartworms. The pills do not need to be given every month. Depending on where you live, this may limit the number of doses given to your dog to one or two a year dramatically reducing their exposure to to the toxic chemicals.
3. Add garlic to their food. Garlic acts as a mosquito repellent. This is a great preventative.
4. Keep standing water away from your property to discourage mosquito breeding.
5. Don’t let your dog stay outside for long periods of time (especially in the evening) during those periods when the temperature is over 64 degrees at all times during a 14 day period.
6. Make a natural mosquito repellent from distilled water with lavender oil and spray it on your dog before he goes out.
7. Have your dog tested every year for heartworm exposure.
This is an injectable type of heartworm prevention that lasts for six months. There have been many adverse reactions to this drug, and the problem with it is that if your dog does have a reaction, it cannot be taken out of the dog’s system. It appears many adverse effects have been reported, including death.
