April is National Heartworm Awareness Month, but lets be real, EVERY month is heartworm awareness month in Texas!
Here in Austin, and all throughout the southern US, heartworm disease is a very common disease in unprotected pets because it is spread by mosquitoes. In some more coastal areas, mosquitoes are present year-round.
Heartworm disease can cause many different health problems and can even be deadly, and even heartworm disease that is treated can cause lasting damage to the inside of the heart. Treatment is also very risky.
Remember to keep your dog or cat on year-round prevention, even pets that are mostly or only indoors.
Visit the American Heartworm Society website for more information on heartworm disease, and ask your vet about testing and prevention options!
