Heartworm preventionIt is spread by mosquitoes and is the most dangerous of all the worms for our pets.

Think about this: wherever there are mosquitoes, there is the risk of heartworm.

When an infected mosquito feeds on your pet's blood, the heartworm larvae enter the blood stream. These larvae mature into worms that can reach up to a scary 30 cm in length!

The worms can eventually become lodged in your pet's heart leading to heart failure. It is at this point that the disease can be fatal. Dogs are more commonly affected by heartworm disease but cats may also be at risk.

Prevention of heartworm is far better than an attempt at a cure but choosing the right heartworm medication can be confusing, especially with so many options on the market.

You need to be aware that many of the intestinal 'all wormer' tablets do not prevent against heartworm infection.

There are topical treatments, oral treatments and a yearly injection for dogs, but your pet must be tested at your local vet before they can commence any prevention.
