Heartworm Prevention in Dogs
Tips for Keeping Your Best Friend Free of Heartworms
Heartworms, so called, are parasitic roundworms known as nemotodes that are carried by mosquitos
and transferred as larvae to a mammal when the mosquito bites. These juvenile parasites reach their adult stage in about ten months and can live in a dog for up to seven or eight years, doing great damage to the pulmonary vessels of the heart and lungs.
Why is Prevention So Important?
An infected dog can go up to a year before showing any signs and by the time it becomes clear your dog is infected a great deal of damage has already been done. Prevention may be costly, but treatment is usually much more so. In addition to the cost, treatment can be painful and draining for the dog and in the end it may be too late.
How is it Prevented?
- A simple and very cost-effective test is available from your local vet clinic, test your dog first to make sure he is not already positive before you begin a preventative plan.
- There are many options available for prevention, the most common is an oral tablet taken monthly. Talk to your vet to determine a plan for you and your dog. Do not let the cost of prevention deter you from making the most cost effective decision for you and the most humane decision for your dog.
At What Age Should Prevention Begin?
Veterinarians themselves debate the most appropriate age to begin monthly prevention, but all seem to agree that treatment should begin at least no later than one year old. This is a decision best made between you and your vet.
Should My Dog Be On Preventatives Year Long, or Just in the Warmer Months?
This is another decision that should be made between you and your vet, and you should always take into consideration your particular climate. If you live in a warm and humid climate you may be better off staying on a 12 month schedule, while if you live an a much colder region your dog's risk may not be as high.
Still, heartworm disease is common in all 50 states and weather patterns are unpredictable these days so your vet may recommend a 12 month schedule to be on the safe side.
Are There Any Extra Steps I Can Take?
One of the best ways to keep the risk of heartworm under control is to cut down on the mosquito population. Empty all pools, trashcans, buckets, etc. of standing water regularly and use a safe form of mosquito repellent.
Remember that in the end, an ounce of prevention is worth a pound of cure. Don't take chances with your best friend.
