As pet parents, we do everything we can to keep our animals healthy. But sometimes your family veterinarian may recommend that your dog or cat see an internal medicine specialist, also known as a board‑certified veterinary internist. This can feel a little overwhelming at first, but for many pets, partnering with an internist provides access to advanced diagnostics, deeper expertise, and the best possible outcomes.

At Peak Veterinary Referral Center, our internal medicine team works closely with your primary veterinarian to diagnose and treat complex medical conditions that require specialized knowledge and equipment.

Here’s how to know when your pet might benefit from seeing an internal medicine specialist.

What Is a Veterinary Internal Medicine Specialist?

A board‑certified internist (DACVIM) is a veterinarian who has completed:

• Four years of veterinary school

• A one-year internship

• A three-year internal medicine residency

• Rigorous board examinations

These specialists are trained to diagnose and treat complicated diseases affecting your pet’s internal organs and body systems, especially when symptoms are chronic, unusual, or difficult to manage.

Signs Your Pet May Need an Internal Medicine Specialist

Your primary veterinarian may recommend a consultation if your pet is experiencing:

1. Chronic or Unexplained Illness

If your dog or cat has symptoms that persist despite treatment, such as vomiting, diarrhea, weight loss, lethargy, or changes in appetite, an internist can dig deeper to uncover the underlying cause.

2. Recurring or Severe Infections

Some infections return again and again, or don’t respond to standard treatment. Internists are skilled in diagnosing and managing:

• Urinary tract infections

• Kidney infections

• Pneumonia

• Tick-borne diseases

• fungal or atypical bacterial infections

They also evaluate whether an underlying immune or metabolic condition is contributing.

3. Endocrine (Hormonal) Disorders

Hormonal diseases often require lifelong management and careful monitoring. Internists routinely treat conditions such as:

• Diabetes mellitus

• Cushing’s disease

  and Addison’s disease

• Hyperthyroidism (cats)

• Hypothyroidism (dogs)

• Insulinoma and other metabolic disorders

These conditions can be tricky to diagnose and stabilize without advanced expertise.

4. Kidney and Urinary Tract Disorders

Internists help pets manage:

• Chronic kidney disease

• Acute kidney injury

• Urinary blockages

• Bladder stones

• Protein-losing kidney disorders

When needed, they also coordinate dialysis options at specialty centers.

5. Liver and Gastrointestinal Diseases

If routine testing isn’t providing answers, internists can perform more advanced diagnostics such as ultrasound-guided biopsies, endoscopy, or specialized blood tests to evaluate:

• Inflammatory bowel disease

• Pancreatitis

• Liver inflammation or failure

• Intestinal cancers

• Gallbladder disease

6. Respiratory Conditions

For pets with coughing, difficulty breathing, or unexplained respiratory symptoms, internists can investigate conditions affecting the lungs and airways, including:

• Asthma

• Chronic bronchitis

• Pneumonia

• Tracheal collapse

• Pulmonary hypertension

7. Immune-Mediated Diseases

When the immune system mistakenly attacks the body, internists step in to diagnose and manage conditions such as:

• Immune-mediated hemolytic anemia (IMHA)

• Immune-mediated thrombocytopenia (ITP)

• Systemic autoimmune diseases

These cases often require intensive, highly specialized care.

Why See a Board‑Certified Internist?

You and your pet benefit from:

✔ Advanced Diagnostic Tools

Internists use specialized equipment not typically available at general practices, including:

• High-resolution ultrasound

• Endoscopy (GI, airway, bladder)

• Fluoroscopy

• Advanced laboratory testing

✔ Specialized Expertise

Complex diseases often mimic one another. Internists know how to interpret subtle test results and create targeted treatment plans.

✔ Collaborative Care

They work hand‑in‑hand with your primary vet to ensure seamless communication and continuity throughout diagnosis, treatment, and long‑term management.

✔ Compassionate Support

Chronic illnesses can be stressful. Internists help guide families through decisions, explain every step clearly, and tailor care to each individual pet.
