Salmonella Infection in Dogs

Salmonellosis is an infection caused by bacteria from the genus Salmonella. The infection is usually confined to the intestinal tract resulting in diarrhea, fever and abdominal cramping. This is a zoonotic condition (meaning it can be transmitted to humans).

Salmonella in dogs can spread from the intestines to the blood and then to other organs, leading to severe illness. Although, disease from Salmonella spp is not common in dogs or cats, the disease can be transmitted to humans through contact with contaminated food and fecal material.

Severity of disease will determine symptoms. Common symptoms associated with salmonellosis include:







Weight loss


Skin disease

Mucus in stool

Abnormally fast heart rate

Swollen lymph nodes

Abnormal vaginal discharge

Miscarriage or spontaneous abortion

Chronic forms of salmonellosis may exhibit some of these same symptoms; however, they will be more severe. These include symptoms:


Weight loss

Loss of blood

Non-intestinal infections

Diarrhea that comes and goes with no logical explanation, which may last up to three or four weeks, or longer
