Your dog can give you so much: love, attention, entertainment, company – and infection. But being alert to some of these problems can help to keep you and your pet healthy.
Whether you own a dog or a cat, a bird or a reptile, a rabbit or fish, you should be aware that your pet can have an effect on your health by infecting you with certain diseases. These are called zoonotic diseases, which are animal diseases that can be transmitted to humans.
You may already know about some of the more common zoonotic diseases: Lyme disease is a bacterial disease transmitted by tick bites; malaria is transmitted by the Anopheles mosquito, and bubonic plague is transmitted by rats, or rather by fleas that become infected by biting the rats. However, you should also be aware of several common zoonotic diseases that can be transmitted by your pet.
Most Common Diseases You can Get From Your Dog are:
- Hookworms and Roundworms – a disease caused by a gastrointestinal parasite. Infection can occur from either ingesting parasite eggs or coming into contact with the larva in the soil. These parasites can be acquired from handling infected soil through gardening, cleaning feces, walking in sand or playing in sandboxes used by animals. Children are most often affected.
- Psittacosis – a bacterial disease you can get by inhaling dust from dried bird droppings.
- Rabies – a viral infection caused by a virus found in the saliva of infected animals and is transmitted to pets and humans by bites. Infected bats, raccoons, foxes, skunks, dogs or cats provide the greatest risk to humans.
- Leptospirosis – a bacterial disease you can acquire from handling infected urine or by putting your hands to your mouth after touching anything that has come into contact with infected dog urine.
- Ringworm – a contagious fungal infection that can affect the scalp, the body (particularly the groin), the feet and the nails. Despite its name, it has nothing to do with worms. The name comes from the characteristic red ring that can appear on an infected person’s skin.All animals can acquire zoonotic diseases, but animals at increased risk include: outdoor pets, unvaccinated animals, pets that are immunocompromised (a suppressed immune system), poorly groomed animals and animals that are housed in unsanitary conditions. People with immune disorders, on chemotherapy or immunosuppressive therapy may be at increased risk of infection.
Animals with zoonotic diseases may exhibit a variety of clinical signs depending on the type of disease. The signs can vary from mild to severe. As a pet owner you should know your animal and be aware of any changes in behavior and appearance.
What to Watch For
Signs of zoonosis include:
- Skin lesions/rashes
- Weight loss
- Bruising under the skin
- Joint swellings
Veterinary Care for Infectious Diseases in Dogs
Your veterinarian will need a good history, including an accurate travel history and complete physical examination in order to make an accurate diagnosis. Since there are so many different kinds of zoonotic diseases, your veterinarian will also do various diagnostic tests. Some of these may include blood tests, cultures, x-rays or ultrasounds.
Treatment depends on the specific diagnosis and may include antibiotics, anti-parasitic drugs or anti-fungal drugs; intravenous fluids; symptomatic care for associated conditions (e.g. vomiting or diarrhea); and analgesic (pain) medication.
Not all animals with zoonotic diseases are serious risks to people, but good hygiene practices should always be observed. Proper education, a good understanding of the disease and its method of transmission are a vital part of home and preventative care. Use proper hygiene and sanitation when handling pets and their excretions and maintain a good program of veterinary care.
