Key Formulas & Equations

Dosage Calculation: Dose (mg) = Weight (kg) × Dose rate (mg/kg)
Fluid Rate: Maintenance = 50-60 ml/kg/day; Shock = 90 ml/kg (dog), 60 ml/kg (cat)
Drip Rate: Drops/min = (Volume × Drop factor) / Time
Body Surface Area (BSA): BSA (m²) = k × W2/3 (k = 0.1 for dogs, 0.1 for cats)
Temperature Conversion: °F = (°C × 9/5) + 32; °C = (°F - 32) × 5/9
Normal Temperature: Dog: 101-102.5°F (38.3-39.2°C); Cat: 100.5-102.5°F (38.1-39.2°C); Horse: 99-101°F (37.2-38.3°C); Cow: 101.5°F (38.6°C)
Heart Rate: Dog: 60-140 bpm; Cat: 140-220 bpm; Horse: 28-44 bpm; Cow: 60-70 bpm
Respiratory Rate: Dog: 10-30; Cat: 20-30; Horse: 8-16; Cow: 12-30
Blood Volume: Dog: 80-90 ml/kg; Cat: 60-70 ml/kg; Horse: 70-100 ml/kg; Cow: 55-60 ml/kg
Packed Cell Volume (PCV): Dog: 37-55%; Cat: 24-45%; Horse: 32-52%; Cow: 24-46%
Total Protein: Dog: 5.4-7.4 g/dL; Cat: 5.9-7.8 g/dL; Horse: 5.5-7.5 g/dL
Anesthetic Calculations: Induction dose = (Dose × Weight) / Concentration
Atropine: 0.02-0.04 mg/kg IM/SQ
Acepromazine: 0.05-0.2 mg/kg IM/SQ
Tiletamine/Zolazepam: 1-2 mg/kg IV (cats)
Caloric Needs: RER = 70 × (W0.75) kcal/day
MER = RER × factor: Inactive = 1.2; Active = 1.6; Puppy = 2.0; Lactation = 4.0
Dehydration: % dehydration = (Pre-treatment weight - Current weight) / Pre-treatment weight × 100%

Core Concepts

Animal Anatomy & Physiology

Study of the structure and function of animal bodies. Comparative anatomy across species is essential for veterinary practice.

Pharmacology

Study of drug actions in animals. Includes pharmacokinetics, pharmacodynamics, drug interactions, and species-specific considerations.

Surgery

Surgical procedures on animals: soft tissue surgery, orthopedic surgery, and emergency surgery. Includes anesthesia, asepsis, and post-operative care.

Internal Medicine

Diagnosis and treatment of diseases affecting internal organs: cardiovascular, respiratory, gastrointestinal, renal, and endocrine systems.

Preventive Medicine

Vaccination programs, parasite control, and wellness exams to prevent disease. Core vaccines for dogs: rabies, distemper, parvovirus, adenovirus.

Diagnostic Imaging

Techniques for imaging animal bodies: radiography (X-ray), ultrasound, CT, and MRI. Used for diagnosis of fractures, tumors, and organ abnormalities.

Zoonotic Diseases

Diseases transmitted from animals to humans: rabies, toxoplasmosis, leptospirosis, and ringworm. Important for public health.

Emergency & Critical Care

Management of life-threatening conditions: trauma, toxicity, shock, and respiratory distress. Includes triage, stabilization, and intensive care.

Worked Examples

Example 1: Drug Dosage

Problem: A 20 kg dog needs amoxicillin at 10 mg/kg. Calculate dose.

Solution:

Dose = 20 × 10 = 200 mg

Example 2: Fluid Rate

Problem: A 10 kg dog needs maintenance fluids. Calculate daily rate.

Solution:

Rate = 10 × 55 = 550 ml/day

Example 3: Temperature Conversion

Problem: Convert 103°F to Celsius.

Solution:

°C = (103 - 32) × 5/9 = 71 × 5/9 = 39.4°C

Practice Problems

Problem 1

Calculate dose for a 5 kg cat needing 5 mg/kg.

Answer: Dose = 5 × 5 = 25 mg

Problem 2

Calculate maintenance fluid rate for a 30 kg dog.

Answer: Rate = 30 × 55 = 1,650 ml/day

Problem 3

Convert 38.5°C to Fahrenheit.

Answer: °F = (38.5 × 9/5) + 32 = 101.3°F

Problem 4

Calculate BSA for a 25 kg dog (k = 0.1).

Answer: BSA = 0.1 × 252/3 = 0.1 × 8.55 = 0.855 m²

Problem 5

Calculate RER for a 20 kg dog.

Answer: RER = 70 × 200.75 = 70 × 9.46 = 662 kcal/day

Problem 6

Calculate dehydration % if pre-treatment weight = 15 kg and current = 14 kg.

Answer: % dehydration = (15-14)/15 × 100% = 6.7%

Problem 7

Identify normal heart rate range for cats.

Answer: 140-220 bpm
