A bacterial infection in dog can be diagnosed based on the symptoms and what veterinarian finds after a physical examination. The veterinarian will go through several lab tests such as allergy test, urinary test, blood test, bacterial culture, fungal culture etc. to figure out the bacteria strain and whether the infection has spread throughout the dog’s body or not. They will take some x- rays, do MRI or ultrasound if required to make a diagnosis.


The treatment of a bacterial infection in dogs depend upon where the infection gained access in to the dog’s body. A dog might be hospitalized based on the seriousness of the infection.

Make sure to follow your veterinarian’s directions carefully to get rid of the infection.
