Cavalier King Charles Spaniel vs Shih Tzu

Two royal lap dogs with centuries of palace pedigree. The Cavalier brings a sporty spaniel spirit wrapped in elegance. The Shih Tzu offers unwavering devotion wrapped in a flowing coat. Both were literally bred to be companions — but their energy levels and health profiles create very different ownership experiences.

Key Differences

1Exercise Needs

Cavaliers need 40-60 minutes of daily walks and enjoy chasing balls. Shih Tzus are content with 20-30 minutes and prefer leisurely strolls.

2Health Costs

Cavaliers face serious breed-wide heart disease (mitral valve disease affects nearly 100% by age 10). Shih Tzus have fewer life-threatening conditions but need eye and dental care.

3Shedding

Cavaliers shed moderately year-round. Shih Tzus have hair rather than fur — they shed very little but require daily brushing to prevent matting.

4Temperament

Cavaliers are eager to please and more adaptable. Shih Tzus have a charming stubbornness and a 'what's in it for me?' attitude toward training.
