Assistance animals and zoonotic disease risk

It is important for veterinarians to evaluate and assess the zoonotic disease risk for assistance animals

In my work as a veterinarian, I understand one of the responsibilities of my profession is to evaluate the health of an animal and prevent zoonotic disease risk and transmission. A zoonotic disease is a disease than can be transmitted from animals to humans and are considered a public health threat. Some zoonotic diseases can be life threatening. Today with #letstalktuesday, Assistance Animals Consulting is discussing the reasons why it is important our veterinarians evaluate and assess the zoonotic disease risk for assistance animals.

At Assistance Animals Consulting, we are veterinarians, recognized experts uniquely qualified to serve the community by providing resources for education, behavioral understanding, and guidance regarding working animals.

Working animals such as assistance animals, provide their handler independence for their daily life function. Many of these working animals have increased public access. The best way to protect assistance animals from zoonotic diseases is to take preventive measures to reduce the chance of contracting them. These preventive measures also help to keep the health of the public at large safe. The veterinarians at Assistance Animals Consulting provide advice and guidance on preventative care recommendations depending on the lifestyle of the handler and disease risk for the working animal. We asses where the handler lives, the assistance animal’s lifestyle, overall health, and other factors prior to making our recommendations.

We’ve provided a short list of some of the most common zoonotic diseases found in dog and cats.


Canine Influenza

Cat Scratch Disease

Cryptococcosis, C. neoformans

Giardia Infection (Giardiasis)

Leptospirosis (Leptospira Infection)

Lyme Disease (Borrelia burgdorferi Infection)

Methicillin-Resistant Staphylococcus aureus Infection (MRSA)

Microsporum Infection – see Ringworm

MRSA (Methicillin-Resistant Staphylococcus aureus Infection)

Mycobacterium tuberculosis Infection (Tuberculosis)


Rickettsia rickettsia Infection (Rocky Mountain Spotted Fever)

Ringworm (Dermatophyte Infection)

Rocky Mountain Spotted Fever (Rickettsia rickettsia Infection)

Roundworm Infection (Toxocariasis)

Salmonella Infection

Sarcoptic Mange (Sarcoptes scabeii Infection)

Tapeworm Infection (Diplyidium Infection)


Toxoplasma gondii Infection (Toxoplasmosis)

Because many of the diseases listed above can be transmitted by animals, prevention and control strategies require the effort not only from our veterinarians, but also from our human healthcare provider partners. At Assistance Animals Consulting, we understand prescribing an assistance animal is a multidisciplinary collaboration. With our interprofessional collaboration, we combine input from physicians and veterinarians to prevent transmission of zoonotic diseases and other health problems before they become life-threatening.

It is also important to understand some people are at a greater risk of contracting a zoonotic disease. These people include children younger than 5 years old, adults over 65 and individuals who are immunocompromised.

The most common way to acquire a zoonotic disease is through direct contact of saliva, blood, urine, mucus, feces or other body fluids of an infected animal. Direct contact can occur with a scratch, bite or from animal licking the hand or mouth. Zoonotic diseases can also be transmitted through indirect contact with objects or surfaces that has contaminated material. An example of this transmission occurs with handling material the animal sleeps on. Vector-borne transmission is another way zoonotic disease is transmitted. This occurs when an infected tick or flea bites a human. Lastly, food borne transmission is the final way a zoonotic disease can be transmitted. For example, this transmission can occur when an assistance animal is feed a contaminated food like a raw diet of undercooked meat.

Zoonotic diseases are most often spread through improper hygiene practices. Handlers using assistance animals and organizations using therapy animals need to be educated on proper hygiene and safety when using a working animal to reduce the transmission of a zoonotic disease. It is important to keep hands clean and wash them with soap and water after contact with an assistance animal. Preventing bites from ticks, and fleas is also important to reduce zoonotic disease transmission. All working animals should have a consistent and effective external and internal parasite control preventative care plan. Lastly, to prevent disease transmission from bites and scratches it is imperative for assistance animals to be non-aggressive and properly trained prior to having full public access.
