🐕 Cavalier King Charles Spaniel

Temperament

Affectionate, gentle, eager to please, sociable. Cavaliers form deep bonds with everyone in the household and tend to follow their humans from room to room. They're famously good with children, other dogs and cats.

Exercise

40–60 minutes of moderate daily exercise plus indoor play. Cavaliers retain some sporting-spaniel drive and enjoy retrieving and scent walks.

Grooming

Long, silky coat with feathering on ears, legs and tail. Brush 3–4× weekly. Bathe every 6–8 weeks. Ear hair needs trimming and ears need weekly cleaning. Eye discharge collects under the eyes — wipe daily.

Health

Mitral valve disease — by age 10, ~70% of Cavaliers have heart murmurs. Annual cardiology screening from age 5 strongly recommended. Syringomyelia (Chiari-like malformation). Hip dysplasia. Episodic falling syndrome. Always buy from a breeder doing MVD and SM screening.

🐶 Shih Tzu

Temperament

Gentle, friendly, slightly aloof, content. Shih Tzus thrive on company and dislike being left alone. They're playful but not high-energy, and generally good with children, other dogs and cats.

Exercise

30 minutes of daily walking plus indoor play is plenty. Brachycephalic features mean they overheat easily — avoid hot weather and strenuous exercise.

Grooming

Long double coat. Daily brushing if kept long; most owners choose a "puppy cut" every 4–6 weeks for ease. Hair around eyes needs daily wiping (eye discharge collects). Top-knot to keep hair out of eyes.

Health

Brachycephalic airway syndrome (mild). Eye issues (proptosis — eye popping out — in trauma). Patellar luxation. Hip dysplasia. Dental disease (small crowded mouths). Generally long-lived for a brachycephalic breed.
