Dogs + Parasites

  • Parvovirus in Dogs

    La infección por parvovirus canino es una enfermedad relativamente moderna que apareció por primera vez en 1978. Debido a la gravedad del proceso y su rápida propagación en la población canina, la parvovirosis constituye un problema de interés público.

  • This handout is designed to give you an overview of some of the internal parasites that can infect your dog. Intestinal worms can be a serious problem in young puppies. Heartworm disease is a major life-threatening problem in dogs. Speak to your veterinarian about the most appropriate parasite control program for your dog.

  • Leishmaniasis is a serious condition spread by flies that can affect dogs, cats, and people. It can severely damage the internal organs or skin and even with treatment, the outcome is often not successful.

  • Leishmaniasis in Dogs

    Es una enfermedad causada por un parásito unicelular que afecta a los mamíferos en muchas partes del mundo y que está extendida por todos los países de la cuenca del Mediterráneo. Hay que tener en cuenta que la enfermedad también puede afectar a las personas, pero no existe una transmisión directa del perro al hombre o viceversa. Se transmite por la picadura de un pequeño mosquito (Phlebotomus spp).

  • Internal Parasites in Dogs

    En general, hay dos tipos de parásitos internos que afectan al perro. En primer lugar están los nematodos o gusanos redondos, de los cuales Toxocara canis (el gusano redondo intestinal más común) y Diarofilaria immitis (el gusano cardiaco) son los principales ejemplos. En segundo lugar tenemos los cestodos o gusanos planos, de los cuales Dipylidium caninum y las especies Taenia y Echinococcus son ejemplos importantes.

  • Lung flukes in North America are parasites called Paragonimus kellicotti that infect the lungs of dogs after they have eaten an infected crayfish or rodents that have eaten infected crayfish. Eggs are then released by the parasite into the dog’s sputum to be coughed out or swallowed and released in the feces to continue the life cycle. Lung flukes can be found anywhere in North America but more commonly around the Mississippi River and Great Lakes. Infected dogs can be symptom-free or may develop cough with sometimes bloody mucus, pneumonia, pneumothorax, lethargy and weakness. Diagnosis can include locating eggs of the parasite from feces or mucus from the lungs. X-rays can also reveal cysts in the lungs caused by the parasite. Treatment requires one of 2 commonly used anti-parasitic medications: Praziquantel or Fenbendazole. Although zoonotic, these parasites won’t transmit directly from dogs to humans.

  • There are many species of lungworm that can cause respiratory problems in dogs. Infection is acquired through either: ingestion of an intermediate host such as snails or slugs, ingestion of animals that have been infected by eating these animals or depending on the species, from an infected dog by contact with saliva, nasal discharge, or contaminated food and water bowls. Lungworms can be found throughout North America and the world with certain species seen in certain areas. Clincal signs can range from asymptomatic to tachypnea, coughing, sneezing, wheezing, respiratory distress or exercise intolerance. The degree of clinical signs is usually proportional to the strength of the dog’s immune system. Diagnosis involves history, physical exam, x-rays and organism identification through either baermann fecal examination or BAL/bronchoscopy. Treatment involves use of specific antiparasitic drugs for various lengths of time depending on type and severity of infection. Prognosis is good but re-infection can occur.

  • Distemper in Dogs

    El moquillo es una enfermedad vírica altamente contagiosa que afecta a los perros domésticos. Otras especies como hurones, mapaches y mofetas también se ven afectadas por esta enfermedad.

  • Pythiosis is a waterborne infection that can infect the GI tract or skin of dogs. It can cause extreme weight loss, vomiting, diarrhea or skin lesions such as ulcerating nodules and draining tracts. This disease is more common in southern regions. Treatment involves surgical removal of all affected material if possible, including limb amputation if indicated. Different antifungal therapies have shown some efficacy and need to be continued long-term. Prognosis for resolution of pythiosis is guarded to poor.

  • Rocky Mountain Spotted Fever is spread by various species of ticks and is not confined just to the Rocky Mountain regions of North America. Clinical signs can be non-specific and cover multiple body systems. Early diagnosis and treatment gives the best prognosis for recovery after treatment with antibiotics. Prevention of tick bites and prompt removal of ticks is important.
