A referral is never needed for emergency care. A referral is always appreciated, but not required, to see our internal medicine, surgery, and cardiology specialists. Although a referral is not necessary to see oncology, a cancer diagnosis is, and we do encourage you to seek the expertise of your family veterinarian to obtain a diagnosis as a first step. Diagnostic imaging is available through our specialty and emergency services, or as a referral from your primary care veterinarian.
