Newfoundland
Sweet, patient, devoted; the 'nanny dog' of literature (Nana in Peter Pan).
At a glance
What they’re great at
Honest challenges
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.
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.
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.

Health to know about
This page can only give breed ranges. The app calculates calories and portions from your dog’s actual weight and life stage, splits them across the right number of meals, and adjusts as they grow.
Emergency red flags
Vomiting, drooling, tremors, collapse, or known ingestion
→ Call ASPCA Poison Control 888-426-4435 or Pet Poison Helpline 855-764-7661 immediately; do NOT induce vomiting unless instructed
→ Save your nearest 24-hour emergency vet's address and phone in your phone TODAY, not during a crisis
Unproductive retching (trying to vomit, nothing comes), rapidly swelling/hard belly, drooling, pacing, sudden distress after eating
→ Drive to the ER immediately. Do not wait to see if it passes. Untreated GDV is fatal within hours
Loud/frantic breathing, brick-red or blue gums, wobbliness, collapse, vomiting in heat
→ Move to AC, wet with cool (not ice) water especially belly/paws, fan, and drive to ER with windows down/AC on - even if the dog seems to recover
Fainting/collapse during activity, night coughing, resting breathing rate over 30-35 breaths/min while asleep, blue-tinged gums
→ Sleeping respiratory rate over 30 warrants a call today; collapse or labored breathing means ER immediately
Straining with little or no urine produced, crying in the litter posture, vomiting, hard painful belly
→ This is a life-threatening emergency, especially in males - ER immediately
The app keeps every Newfoundland red flag on your phone and opens them with no connection at all — which is the whole point at 2am in a car park. Add it to your home screen and it works like any other app.
