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.
Leptospirosis is a bacterial disease of dogs and other mammals that primarily affects the liver or kidneys. The bacteria (Leptospira) that cause leptospirosis, commonly called leptospires, thrive in water. Infected or recovered carrier dogs may act as a source of the infection. There are three main forms of the disease. Antibiotics such as penicillin, ampicillin, and amoxicillin, are reasonably effective against the acute stages of leptospirosis if begun early, although most affected dogs require intensive care in the veterinary hospital.
Lyme disease is a growing concern as ticks migrate. It often presents as a lameness but can also show up as kidney failure. Treatment with one of the following antibiotics doxycycline, amoxicillin, or azithromycin lasts for 4 weeks. Preventives are available to help protect your dog from this disease.
Melioidosis is a bacterial infection that is typically associated with tropical regions. The bacteria that causes melioidosis, Burkholderia pseudomallei, is usually found in soil and water. It is introduced to these areas when it is shed in the milk, feces, urine, or wound drainage of infected animals. In dogs, melioidosis can cause a variety of clinical signs. It mimics a number of other diseases; therefore, it is sometimes referred to as the great imitator. Treatment of melioidosis requires prolonged courses of antibiotics. The organism is resistant to many antibiotics, meaning that specific, expensive antibiotics may be required.
The Ebola virus is very contagious and is transmitted through blood, body fluids and tissues, but not through air, water, or food. Ebola affects humans, non-human primates, and is carried by fruit bats. Other species do not appear to be affected although there has been evidence of exposure to the disease in dogs, cats, and other domestic animals. Domestic animals are not believed to transmit the virus; however, there is a risk that they could transmit body fluids such as saliva on their fur to other humans. Any potential exposure to Ebola should be reported to your veterinarian who will contact the Center for Disease Control (CDC).
COVID-19 is a human respiratory disease that was initially discovered late in 2019. This disease is caused by a new coronavirus, SARS-CoV-2, that has not previously been identified in humans. Physical distancing, or social distancing, is one of the most effective strategies available to reduce the spread of COVID-19. While social distancing, walking your dog is fine as long as you are feeling well and can remain at least 6 feet away from other people. If you have cats, find new ways to play with them indoors. Many veterinary clinics are adjusting their policies to reflect social distancing guidance related to COVID-19. If your pet needs veterinary care (or if you need to pick up medication, a prescription diet, etc.), call your veterinary hospital first to determine how to proceed.
Rabies is one of the most devastating viral diseases affecting mammals, including dogs and humans. It is a fatal disease caused by infection with the rabies virus. Rabies virus is found throughout the world, including North America, Central and South America, Asia, Africa, the Middle East, and some parts of Europe. Following a bite from a rabid animal, the disease progresses in stages. Dumb rabies is the more common form in dogs. There is progressive paralysis involving the limbs, distortion of the face and a similar difficulty in swallowing. Vaccination is the cornerstone of rabies prevention.
Ringworm is the common name given to a fungal infection of the superficial layers of the skin, hair, and nails. The common name of ringworm is somewhat misleading, in that it is not an infection caused by a worm, and the infected areas are not always ring-shaped. In the dog, ringworm lesions usually appear as areas of hair loss (alopecia) that are roughly circular.
H1N1 influenza virus emerged in pigs as a genetic sharing of DNA from both human and swine influenza viruses. It caused a deadly pandemic in 2009 and continues to be an important cause of illness today. Pets including cats and dogs can be infected from their owners and become ill. It is not yet thought to transfer from pets to humans. Because influenza viruses appear to be capable of swapping genes, there is potential for new variants of influenza viruses to be generated at any time leading to another pandemic of severe disease in humans and other animals. Good hygiene and exposure restriction should be taken immediately if there is any sign of influenza-like infection to restrict spread between humans and between humans and their pets or domestic animals.
Ticks are parasites that feed on the blood of their host and can in turn transmit diseases to your pets or even you. They are prolific breeders and their life cycles can extend through multiple seasons. Prompt removal or use of preventatives limit or prevent the spread of disease, or kill the ticks.
