Heartworm Disease

Heartworm disease is a potentially fatal disease spread by mosquitos. While not as common in Pennsylvania as it is in southern states like Florida, Mississippi and the Carolinas, widespread adoption from across the country can bring heartworm positive dogs into our area making all dogs at risk. Heartworm disease has been diagnosed in all 50 states.

If a mosquito bites an infected dog, it can pick up heartworm larvae. If that mosquito then bites your dog, the mosquito can inject the microscopic larvae called microfilariae into the bloodstream. In an unprotected dog, microfilariae will mature into adult heartworms inside the heart and pulmonary arteries in about seven months. Adult worms can grow to be more than a foot in length and cause serious damage to the heart and lungs. Untreated heartworm disease may result in chronic heart and lung disease which may progress to congestive heart failure and death.
Heartworm disease is simple to prevent, but it can be costly and sometimes risky to treat. A monthly chewable tablet such as Sentinel protects your dog against heartworm disease as well as other parasites like roundworms, hookworms and whipworms. Easy to use, safe for your pet and affordable, this is the preferred product at PVH for preventing heartworm infection in dogs. If monthly chewables aren’t your thing, we also have Proheart 6 given as an injection under the skin every six months at our office to provide year round heartworm protection.
Why risk such a serious illness for your dog when it can be so easily prevented with a monthly or twice yearly medication? Ask us about heartworm protection for your dog today.

Read What Our Clients Say

    Very nice pet hospital. We were extremely pleased. Impressed by the education they give you as well. Our dog had her teeth cleaned and the nurse spent 10 minutes going over post-op procedures. Also we needed to come back in one week to have sutures looked at and they don't charge you an office visit for that like Leader Heights Animal Hospital would do


    I am extremely happy with the care that my puppy Cody received when he had his recent hip surgery. I highly recommend Patton Veterinary Hospital.

    I would absolutely recommend Patton to anyone who has pets. Fabulous service every time by all the staff. Thank you


    The entire staff is courteous, friendly, and helpful. They all seem to have a true love for all pets. They follow-up promptly and we have never had a problem with any of the doctors (Dr. Doug is our primary) or any of the other staff.
