Most of us are not exactly excited about looking into our pet’s mouths (I only see 2 teeth – the fangs!). But when it comes to pet dental care, the saying “an ounce of prevention is worth a pound of cure” is absolutely true. It has been reported that by 3 years of age, 85% of cats and dogs have some form of dental disease. Felton Veterinary Hospital is here to give you the basics of this common but preventable problem.
What Happens in Heartworm Disease
By Wendy C. Brooks DVM, DABVP
Heartworm Disease vs. Heartworm Infection
Before reviewing the clinical signs seen in heartworm disease, an important distinction must be made between heartworm disease and heartworm infection. Heartworm infection by definition means the host animal (generally a dog) is parasitized by at least one life stage of the heartworm (Dirofilaria immitis). Dogs with heartworms in their bodies do not necessarily have adult worms in their hearts; they may have larval heartworms in their skin only. Dogs with heartworms in their bodies are not necessarily sick, either. Dogs with only larvae of one stage or another are not sick and it is controversial how dangerous it is for a dog to have only one or two adult heartworms. These dogs are certainly infected but they do not have heartworm disease.
