Heartworm Disease Prevention in Allen, TX


Protect Your Pet with Trusted Care at Country Creek Animal Hospital


Heartworm disease is a serious and potentially life-threatening condition that affects dogs and cats throughout Texas—including right here in Allen. At Country Creek Animal Hospital, we’re committed to helping pet owners protect their furry companions with effective, year-round heartworm prevention and education.


What Is Heartworm Disease?


Heartworm disease is caused by parasitic worms (Dirofilaria immitis) that are spread through the bite of an infected mosquito. Once inside your pet, these worms grow and live in the heart, lungs, and blood vessels—causing permanent damage and even death if left untreated.

Heartworm disease is especially common in warm climates like Texas, where mosquitoes are active nearly year-round. Even indoor pets are at risk.


Why Heartworm Prevention Matters


Heartworm disease in dogs can lead to:


  • Severe lung disease
  • Heart failure
  • Organ damage
  • Sudden death in advanced cases


In cats, heartworm infection can be more difficult to detect and is often misdiagnosed. Even a small number of worms can cause significant respiratory problems.


The good news? Heartworm disease is completely preventable.
