The NAVLE (North American Veterinary Licensing Examination) is the primary licensure exam for veterinarians in the United States and Canada. It tests your ability to apply clinical knowledge across a broad range of species and disciplines. This free DVM practice test PDF lets you study the most-tested concepts offline and track your readiness before exam day.
The NAVLE is a computer adaptive test (CAT) administered over two days. Passing requires a scaled score of approximately 425, and the exam draws from clinical scenarios spanning small animals, equines, food animals, and public health. Use the PDF below to print your own practice questions and drill the content areas most likely to appear on your exam.
The NAVLE tests clinical reasoning across internal medicine, surgery, pharmacology, public health, and diagnostic imaging. Understanding the species-specific differences and high-yield clinical presentations gives you a major advantage.
Diabetes mellitus appears differently in dogs versus cats. Dogs most commonly develop insulin-dependent diabetes and often present with polyuria, polydipsia, polyphagia, and weight loss; intact females are overrepresented due to progesterone-induced insulin resistance. Cats more frequently develop type 2 diabetes with peripheral neuropathy causing plantigrade stance. Hypothyroidism in dogs is characterized by lethargy, weight gain, cold intolerance, dermatologic changes (bilaterally symmetric alopecia, hyperpigmentation), and bradycardia; diagnosis relies on low total T4 with elevated TSH. Feline hyperthyroidism presents with weight loss despite polyphagia, tachycardia, and hypertension; radionuclide (radioactive iodine I-131) therapy is considered curative.
Gastric dilatation-volvulus (GDV) is a life-threatening emergency in large, deep-chested breeds. Radiographically, the "double bubble" or compartmentalized gas pattern on right lateral view is classic. Treatment requires immediate decompression, IV fluid resuscitation, and surgical correction with gastropexy to prevent recurrence. Intestinal obstruction presents with vomiting, abdominal pain, and dilated loops on radiograph; linear foreign bodies in cats can cause plication of the intestine. Orthopedic conditions commonly tested include cranial cruciate ligament rupture (drawer sign, tibial thrust) and capital femoral physeal fractures in young cats.
NSAIDs are toxic to cats at doses safe for dogs — cats lack the glucuronidation pathway required to metabolize many NSAIDs. Drug withdrawal times are critical for food animal medicine; exam questions often involve meat or milk withholding periods for antibiotics and anthelmintics. Veterinarians are DEA-registered practitioners required to maintain controlled substance logs and comply with state board regulations for Schedule II–V drugs.
Rabies protocols require knowledge of state-specific quarantine periods and which species are considered reservoirs versus dead-end hosts. Reportable diseases vary by state but commonly include brucellosis, anthrax, equine encephalitis, and Newcastle disease. Leptospirosis is transmitted via urine-contaminated water; brucellosis in dogs (Brucella canis) can infect humans handling reproductive tissues; ringworm (dermatophytosis) is among the most common veterinary zoonoses.
Thoracic radiographs in small animals require systematic evaluation of the cardiac silhouette (vertebral heart score >10.5 suggests cardiomegaly in dogs), pulmonary vasculature, and pleural space. Abdominal views assess organ size, position, and the presence of free gas or fluid. On the NAVLE, distinguishing between a megaesophagus (dilated esophagus on lateral thoracic view) and a mediastinal mass is a high-yield skill.
Print the PDF and work through each question without looking at the answer key first. Time yourself at a pace of approximately 90 seconds per question to simulate CAT conditions. After completing a section, review every incorrect answer and identify which content domain it belongs to — internal medicine, surgery, pharmacology, public health, or radiology. Build a targeted review list from your weak areas and return to those sections in your Plumb's Veterinary Drug Handbook, Ettinger's Textbook of Veterinary Internal Medicine, or equivalent reference.
Combine PDF practice with online adaptive question banks for the best results. Offline drilling with printed questions reinforces retention differently than screen-based testing, making both formats valuable in a complete NAVLE study plan.
