The ultimate goal of the veterinary team is to provide the services that help family pets live long and healthy lives. More and more pet owners recognize the need for preventive health care for themselves and for their pets. Preventive health care includes regular physical examinations and vaccinations against common diseases. A physical examination performed at least once a year helps to identify any potential problems that a pet may be developing. This yearly exam allows the veterinarian to provide treatment that may keep a disease or condition from getting worse.
