Penicillin antibiotics are used to treat treat urinary tract infections, upper respiratory tract infections, lower respiratory infections, skin infections, bacterial infections, gastrointestinal infections, meningitis, and pneumonia. They work by killing the bacteria that is causing the infection.

Vets often prescribe amoxicillin to prevent or treat bladder and upper respiratory infections, as well as cuts and wounds and infections in the mouth.
