CCAT CCAT Nutrition, Weight Management and Wellness 1 — Questions and Answers
Question 1: Excess body weight in dogs most directly worsens orthopedic conditions because it:
- Decreases blood viscosity
- Increases mechanical load on joints and accelerates cartilage degradation (Correct answer)
- Reduces inflammation
- Improves muscle tone
Correct answer: Increases mechanical load on joints and accelerates cartilage degradation
Every pound of excess weight multiplies the compressive force on weight-bearing joints, accelerating cartilage breakdown and worsening conditions like hip dysplasia and osteoarthritis.
Question 2: Which body condition scoring (BCS) system is most commonly used in veterinary practice to assess canine obesity?
- 1–5 scale (Purina)
- 1–9 scale (Purina/WSAVA) (Correct answer)
- 1–10 scale (Hill's)
- 1–100 scale (BMI equivalent)
Correct answer: 1–9 scale (Purina/WSAVA)
The 1–9 scale developed by Purina and adopted by WSAVA is the most widely used standardized system, with a score of 4–5 being ideal.
Question 3: In a canine rehabilitation patient, which nutritional component is MOST critical to support muscle repair after orthopedic surgery?
- Simple carbohydrates
- Dietary protein and essential amino acids (Correct answer)
- Saturated fats
- Soluble fiber
Correct answer: Dietary protein and essential amino acids
Adequate high-quality protein provides the amino acids necessary for muscle protein synthesis and tissue repair during post-surgical recovery.
Question 4: Omega-3 fatty acids (EPA and DHA) are recommended in canine rehabilitation nutrition primarily for their role in:
- Increasing caloric density
- Reducing inflammatory mediators and supporting joint health (Correct answer)
- Improving coat color
- Increasing red blood cell count
Correct answer: Reducing inflammatory mediators and supporting joint health
EPA and DHA competitively inhibit arachidonic acid metabolism, reducing the production of pro-inflammatory prostaglandins and cytokines.
Question 5: The ideal strategy for weight loss in an obese canine rehabilitation patient is:
- Abrupt caloric restriction to 50% of maintenance
- Gradual caloric reduction (10–20%) combined with controlled low-impact exercise (Correct answer)
- High-fat diet to increase satiety
- Unlimited exercise without dietary changes
Correct answer: Gradual caloric reduction (10–20%) combined with controlled low-impact exercise
Gradual caloric reduction combined with rehabilitation-appropriate exercise preserves lean muscle mass while safely reducing adipose tissue.
Question 6: Which measurement, combined with BCS, provides the most complete assessment of canine body composition in a rehabilitation setting?
- Coat quality index
- Muscle condition score (MCS) (Correct answer)
- Fecal scoring
- Urine specific gravity
Correct answer: Muscle condition score (MCS)
The muscle condition score evaluates the degree of muscle wasting (sarcopenia) independently of fat stores, guiding nutritional and exercise interventions.
