Why it matters
Honest challenges
Summer is dangerous, not just uncomfortable
Coat or airway makes heat a genuine physical limit.
What helps: ['Dawn and dusk walks; midday is rest time', 'Cooling mat, shade, and AC access always (see Home Setup)', 'Learn the heatstroke signs in SOS - minutes matter']

Built beautiful, breathes carefully
Short airways set real physical limits.
What helps: ['Exercise in cool hours only; weight is the #1 breathing variable', 'Harness always - never a collar on this airway', 'Know the breathing-emergency signs in SOS']

What you can do
Exercise & training
Exercise: Moderate - 45-60 min/day
Training profile — Brachycephalic / low-impact companion: Exercise quota is modest but enrichment quota is not - these are clever, people-focused dogs. Air conditioning is safety equipment, not luxury.
Sports and outlets that suit them: Agility (surprisingly good) · Trick titles
What you can do
Grooming & coat
Grooming: Very low - occasional brushing; protect prominent eyes.
Shedding: Light.
