Veterinary Internal Medicine for Dogs & Cats in Lancaster, PA

Some conditions don’t have simple answers. When symptoms continue, diagnoses remain unclear, or multiple body systems may be involved, a deeper medical investigation is often needed.

At Lancaster Veterinary Specialties, our board-certified veterinary internist, Dr. Rodriguez, focuses on identifying the underlying causes of illness rather than only controlling symptoms. We evaluate chronic digestive problems, unexplained weight loss, hormonal disorders, respiratory disease, immune-mediated conditions, and other complex medical cases.

We work closely with your primary veterinarian so testing, treatment, and follow-up care remain coordinated and organized for your pet.

When Is an Internal Medicine Specialist Needed?

Your veterinarian may recommend referral when a condition persists, initial treatments have not worked, or laboratory results raise additional questions.

Pets are commonly referred for:

  • ongoing vomiting or diarrhea
  • unexplained weight loss or poor appetite
  • chronic coughing or breathing problems
  • anemia or abnormal bloodwork
  • fever of unknown origin
  • endocrine disorders (thyroid, diabetes, adrenal disease)
  • kidney or liver disease
  • immune-mediated or infectious disease

Internal medicine evaluates how body systems interact and identifies why symptoms are occurring. This approach is especially helpful when multiple organs may be involved or when a condition requires long-term management.
