Finding the right heartworm medicine to prevent your cats and dogs contracting this serious parasitic illness. Choosing daily or monthly heartworm pills, branded or generic products can be a minefield. Look no further for all the information to help you choose the best pet meds for your furry friends.

Once heartworm disease has taken hold treatment to destroy the parasite is extremely risky for your pet. Treatment may last years and is not always successful. Without regular preventative heartworm medicine pets may contract the heartworm parasite whenever mosquitoes are active. The American Heartworm Society recommend using a preventative regularly, ideally all year but at the very least, during warmer months.

Incidences of the disease have now been reported all over the United States, it is no longer the preserve of swampy, hot areas. As mosquitoes adapt and travel they take the parasite with them, ready to infect our pets.

There are two ways of giving preventative medicines. Heartworm Pills or spot on treatments may be chosen. This site is dedicated to heartworm pills which are the most popular form of preventing the disease. Products are sold for use in all sizes of dog and cat. While a prescription is required in some countries, in others these heartworm pills are sold prescription free.

Most modern products are for use on a monthly basis but there are daily tablets available too which are particularly useful for larger breeds of dog. Heartworm for dogs is a widely known about problem but the rate of heartworm in cats is also growing. Luckily preventative treatments are now available for both sorts of pet.

Whichever make of heartworm pill you chose, ensure your pet is free from the disease before initiating treatment. Also, always use a product sold for your size and species of pet. Cats are often sensitive to ingredients used in dog pet meds so it is never a good idea to use such products indiscriminately on all your pets.

If two months or more have elapsed since the last monthly pill speak to your vet about a heartworm test.
