Dogs + Infectious Diseases

  • Coccidia are single-celled organisms that can act as parasites after infecting your dog through the gastrointestinal tract. The most common form affecting dogs, Isospora, is not a concern for infecting people. They are highly resistant to environmental conditions and cleanliness is important to prevent re-infection. Treatment is often simple with the appropriate antibiotics prescribed by your veterinarian.

  • COVID-19 is a disease caused by the coronavirus SARS-CoV-2. Current evidence suggests that person-to-person spread is the main source of infection. While there is evidence of transmission from humans to dogs and cats, it does not appear common. If you suspect that you are ill with COVID-19, you should take the same precautions with your pet as you would with people.

  • Diarrhea is a symptom of an underlying problem that may be minor or very serious. Some cases may resolve on their own or with minimal treatment, while other cases require in-depth diagnostic testing and more aggressive treatment to address the underlying condition. The possible causes, diagnostic tests, and treatment protocols for diarrhea in dogs are numerous and are explained in this handout.

  • Discospondylitis is a bacterial or fungal infection of the intervertebral disks and the adjacent vertebral bones. It primarily affects dogs, though rarely can affect cats. It affects large breed dogs more often and generally starts clinically as back pain. The diagnosis and treatment of this condition are outlined in this handout.

  • Distemper virus is a highly contagious disease that can affect multiple body systems and is potentially fatal. Puppies are most susceptible, and respiratory, gastrointestinal, or neurologic signs may be seen. Vaccines are available and are highly effective at preventing disease.

  • Ehrlichiosis is a tick-borne bacterial (Ehrlichia) infection spread by the brown dog tick found in many areas of North America. There appear to be three stages of disease: acute, sub-clinical, and chronic or clinical. Abnormal findings on initial lab work include thrombocytopenia, anemia, hyperglobulinemia, and proteinuria. In-clinic ELISA tests can be used to screen for exposure but will be negative if the infection is new. Blood can be sent for PCR testing to demonstrate infection and to determine the species of Ehrlichia. Prevention includes minimizing exposure to ticks and use of tick prevention medication regularly.

  • 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.

  • Lyme Disease in Dogs

    La enfermedad de Lyme está causada por una espiroqueta, Borrelia burgdorferi. Una espiroqueta es un tipo de bacteria. La enfermedad de Lyme se transmite a los perros a través de la picadura de una garrapata. Una vez en el torrente sanguíneo, el organismo de la enfermedad de Lyme será transportado a diferentes partes del cuerpo y puede llegar a las articulaciones. Antes se pensaba que sólo un tipo concreto de garrapatas podían transmitir la enfermedad, pero ahora parece ser que muchos tipos de especies están implicadas. El tipo más común de garrapata portadora de la enfermedad de Lyme es la garrapata ciervo.

  • Flea and tick prevention consists of a variety of products used to control flea and/or tick infestations on your pet and to prevent infestations inside the home. Fleas and ticks can be found worldwide. Fleas can live in many climate zones, but they prefer humid and shady areas, such as under leaf litter. Ticks can also live in many climate zones, and prefer humid and shady environments, especially areas with woods, shrubs, weeds, and tall grasses. Prevention is key to avoid infestations in your home, severe allergic reactions (in both pets and people), and to prevent disease. Many flea and tick preventives are available. Your veterinarian will help you find an appropriate product that works best for your and your pet.

  • Giardiasis is an intestinal infection caused by a microscopic protozoan. These parasites attach themselves to the intestinal wall and the damage causes an acute, sudden onset of foul-smelling diarrhea. Diagnosis may be by routine fecal flotation or presumptively based on clinical signs. Fenbendazole and metronidazole are the drugs most commonly used to treat giardiasis.
