  • Heartworm Disease in Dogs

    La enfermedad de los gusanos del corazón o dirofilariosis es una enfermedad grave y potencialmente fatal. Está causada por un parásito sanguíneo llamado Dirofilaria immitis.

  • Flea allergy dermatitis (FAD) is a leading cause of allergic reactions in dogs. It is the antigens or proteins in the flea saliva that cause an intensely itchy response to sensitive dogs. Itching and hair loss in the region from the middle of the back to the tail base and down the rear legs (the flea triangle) is often associated with FAD. Strict flea control is essential in the prevention and treatment of FAD. Occasionally corticosteroids are used to reduce the itching in patients with severe signs of FAD.

  • Successful flea control involves both eliminating fleas from your dog and controlling fleas in your environment. Dogs and cats share the same fleas, and fleas can travel from one animal to another. Therefore, it is important that all pets in your home are on a flea preventive program. Successful flea control includes treating both your pet(s) and the environment.

  • Giardiasis is an intestinal infection in humans and animals, caused by a microscopic protozoan parasite. The parasite occurs worldwide and is a common cause of "Traveler's Diarrhea" in people. Outdoor enthusiasts who inadvertently consume contaminated water may develop "beaver fever", which is another name for giardiasis in people.

  • Harvest mites, also known as red bugs, trombiculid mites, scrub-itch mites, berry bugs or, in their larval stage as chiggers, are mites that are commonly found in forests and grasslands. Harvest mites are relatives of spiders. They are nearly microscopic measuring only 1/100 of an inch (0.4 mm) and have an orange hue. A common species of Harvest mite in Northern America is Trombicula alfreddugesi.  

  • Heartworm disease is a serious and potentially fatal disease. It is caused by a blood-borne parasite known as Dirofilaria immitis. Adult heartworms may live up to five years and, during this time, the female produces millions of offspring called microfilaria. You can prevent your dog from getting heartworms by using a heartworm preventive.

  • Heartworm disease or dirofilariasis is a serious and potentially fatal disease. It is caused by a blood-borne parasite known as Dirofilaria immitis. Treatment usually consists of several parts including an injectable drug to kill adult heartworms, antibiotics, and treatment to kill microfilaria. There is some risk involved in treating dogs with heartworms, although fatalities are rare.

  • Hookworms are intestinal parasites of the cat and dog that get their name from the hook-like mouthparts they use to anchor themselves to the lining of the intestinal wall. A large number of hookworms can cause inflammation in the dog's intestine as well as a life-threatening decrease in the number of red bloods cells, which is called anemia. This problem is most common in puppies, but can occur in adult dogs.

  • Whipworm Infections in Dogs

    Los gusanos látigo son parásitos intestinales de una longitud aproximada de 6 mm (1/4 inch). Viven en el ciego y el colon (intestino grueso) de los perros donde provocan irritación en el revestimiento de estos órganos. Los gusanos látigo provocan diarrea acuosa y sanguinolenta, pérdida de peso y debilidad generalizada. Son uno de los gusanos más patogénicos en perros.

  • Tapeworm Infection in Dogs

    ¿Qué son los gusanos planos? Los gusanos planos son gusanos intestinales que están compuestos por pequeños segmentos, cada uno aproximadamente 3-5 mm (1/4 – ½ ) de largo. A diferencia de los gusanos redondos que viven libremente en el tracto gastrointestinal, los gusanos planos se adhieren a la pared del intestino delgado usando sus partes bucales.
