Why it matters
Honest challenges
Alone time is genuinely hard
Bred to work or live beside a human all day - solitude was never in the job description.
What helps: ['Train it like a skill: the Alone-Time guide builds tolerance in micro-doses from day one', 'The frozen-KONG-only-when-you-leave ritual turns departures into jackpots', "Cover long days honestly: a midday walker, daycare 2-3x a week, and a camera to know (not guess) how they're doing"]

The fur is a lifestyle
Heavy-shedding coat with seasonal blowouts.
What helps: ['The weekly rake routine in the Grooming Kit halves it', 'Robot vacuum on daily patrol (see Home Setup)', 'A professional deshed blowout during coat-blow weeks saves the house']

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']
