When you take your pet to the vet for an annual visit, you're probably thinking the most important parts are vaccinations, tests, blood work, or prescription medication renewals. All of these are vital pieces of what your veterinarian does to keep your pet healthy, but often the most important aspect of a visit is the physical exam. Examining your pet's body gives your veterinarian a clear picture of overall health and helps him or her make quality decisions for your pet's care.
