Published odds4.26×Against a Labrador Retriever, for having ever presented with heat illness.
Heat multiplier1.9×Product policy, capped far below the raw odds. It is the starting point the app then adjusts for weight, coat, body condition and breathing.

The mechanism
Why heat reaches a Greyhound first
Where that comes from
Hall, Carter & O'Neill 2016, VetCompass. Not brachycephalic: sprint metabolism and low body fat.
What the number is not
The odds are for whether a dog of that breed ever presented with heat-related illness. They set the RANKING; they are not a multiplier on how long a dog may be outside, and the app never uses them as one.
Tell any vet before sedation
Make sure any vet putting [name] under anaesthesia knows he is a Greyhound before the drugs are chosen. Sighthounds process some anaesthetics differently: the old thiobarbiturate drugs are to be avoided entirely, and recovery from some injectables runs slower than the standard chart expects.
Water safety
Can a Greyhound swim?
Poor swimmer
Free forever in the app. The swimming verdict and the cool-down protocol are the two pieces of content that exist to prevent a drowning and a death, and neither is ever behind a paywall.
Very low body fat means very little natural floatation, and thin skin chills fast. Many greyhounds simply sink. Vest on, and keep sessions short.
What to own
The gear that earns its place
Before anything else
A wide, padded sighthound collar or a Y-harness. Never a thin collar.
His head is narrower than his neck, so ordinary collars slip off backwards, and a thin band concentrates all the pressure on a slim throat. Wide and padded, or chest-based.
Wide sighthound collar or Y-harness
A slim head slips ordinary collars, and a thin neck concentrates pressure. Wide and padded, or chest-based.
Cooling mat
Thin coat, thin skin: he takes heat from sun and hot ground fast, and a cool surface offloads it fast too.
Booties for hot pavement
Thin paw pads and low body fat give little insulation from a hot road.
Portable water bottle with trickle bowl
Sprint bursts generate enormous heat in seconds. Offer small drinks and real rest between them.
Dog life jacket with a grab handle
Almost no body fat means almost no floatation - many greyhounds simply sink. The vest is what makes water an option at all.
Every day
The daily jobs a Greyhound actually needs
Not a generic list. These are the tasks this breed’s anatomy earns — the same set the app seeds a new profile with — and each one carries the guidance it comes from.
Brush teethdaily
Daily brushing removes plaque before it hardens into tartar, the main preventable cause of dental disease.
American Veterinary Dental College (AVDC): daily tooth brushing is the standard recommendation.
Check and clean earsweekly
Wax and moisture build up in ears and can lead to infection, especially in floppy or hairy-eared dogs.
Veterinary guidance. Frequency ranges from weekly to as directed by your vet. · cadence is a range, not a clinical number
Trim nailsevery 3–4 weeks
Overgrown nails change how a dog stands and walks and can strain joints over time.
General veterinary guidance. Cadence depends on how much the nails wear down naturally. · cadence is a range, not a clinical number
Nose balm (if dry)as needed
A dry or crusted nose can be soothed with a dog-safe balm, but many dogs need nothing.
PROVISIONAL: no clinical frequency is established. Apply only if the nose is visibly dry. · cadence is a range, not a clinical number
Bowls and meals
Water, food, and the gap between them
Water
Small amounts often around exercise. A deep chest carries bloat risk, so no huge gulped drink straight after a sprint.
Bowls
A slow feeder if he inhales food, and split meals rather than one - the deep chest is the reason.
Food and effort
Not a flat-faced breed, so bringing food back up is not the breed theme it is for a Bulldog. The deep chest is the thing to respect, and what the evidence points at there is eating speed, meal size and bowl height rather than the gap between dinner and a walk.
Particular to this breed
Risks a Greyhound carries that most dogs do not
Sprint heat load
A greyhound generates more heat in a thirty-second sprint than most dogs do in a whole walk. The danger is bursts, not distance.
Thin skin tears
His skin marks and tears far more easily than other breeds. Rough play and brambles do real damage.
If they overheat
Cool first. Call while you cool.
The cool-down for a Greyhound
Cool first, drive second. Pour cool (not icy) water over him, air moving, vet with AC on. Greyhounds over-chill quickly once wet - stop active cooling as soon as he perks up.
Stop, whatever the number says
Heavy or frantic panting, lagging behind or wanting to stop, unsteadiness, or gums that look dark, grey or brick red. Get out of the heat and start cooling immediately.
The whole emergency screen is free forever and works with no signal — the steps, your own vet’s number, and the nearest 24-hour hospital, all held on the phone.
