Extensive Diagnostics for Pets with Complex Conditions

Internal medicine focuses on diagnosing and managing diseases that affect your pet’s organs and body systems. These conditions can be subtle, with vague symptoms like weight loss, increased thirst, vomiting, or behavioral changes—and often require lab work, imaging, and sometimes even a bit of detective work.

Our team uses a full suite of in-house diagnostics, including bloodwork, urinalysis, fecal testing, radiographs, and more to evaluate your pet’s internal health. Once we identify the issue, we’ll develop a treatment plan tailored to your pet’s specific condition, needs, and lifestyle.

Common Internal Medicine Conditions We Treat in Pets

Some of the most common internal conditions we diagnose and manage include:

Icon Gastrointestinal

Gastrointestinal Disease

Chronic vomiting, diarrhea, or appetite loss may be signs of underlying issues such as inflammatory bowel disease, food allergies, or intestinal infections. We work to pinpoint the problem and relieve your pet’s discomfort.

Icon Endocrine

Endocrine Disorders

Conditions like diabetes, Cushing’s disease, and thyroid imbalances require ongoing management and monitoring. We’ll walk you through your pet’s treatment plan and make adjustments as needed for the best quality of life.

Icon Liver

Liver Disease

The liver plays a vital role in digestion and detoxification. Our diagnostic tools help us detect early signs of liver dysfunction and begin appropriate therapy before symptoms worsen.

Icon Kidneys

Kidney Disease

Chronic kidney disease is common, especially in senior pets. We monitor kidney values, hydration, and overall health to slow disease progression and maintain your pet’s comfort.

Icon Oncology

Oncology (Cancer)

A cancer diagnosis is never easy, but we’re here to guide you through it with compassion and clarity. We offer supportive care, diagnostics, and help coordinate with local oncology specialists when advanced treatment is needed.

If your pet is facing one of these conditions, we're here to help.
