A temperature reading on its own can’t tell you whether an activity is appropriate for the dog in front of you.
Shade, direct sun, humidity, airflow and the surface all change the environment. The individual dog matters too — their size, build, coat, fitness, health, acclimatisation and current condition all influence how they cope.
Then add the activity itself.
A dog resting in the shade and a dog running, training or highly aroused at the exact same air temperature are dealing with very different thermal demands.
That’s why heat safety needs context.
Dog + environment + activity = actual risk.
Use the forecast as information, not as a substitute for judgement. Watch the dog, adjust the workload, change the environment where possible, and reassess as conditions change.
There is no single number that can do that thinking for you.
