Useful information about exercising your dog in the heat. Lets not overreact and make our dogs miserable by not exercising them at all when it gets hot. If we educate ourselves with facts, observe our dogs and use a bit of common sense, then we can find the right amount of exercise for our dogs whatever the temperature :)

THERMOMETER vs PANT-O-METER:
MONITORING DOGS THAT COULD EXPERIENCE HEAT STRESS
A burning question at the start of another warm day: Do we need to use a thermometer to monitor dogs for early signs of thermal stress?
A thermometer will give an objective and measurable reading of the dog's core temperature at the time when it is checked.
Reading our dogs' behavioural signs will however provide us with a continuous stream of feedback how hot the dog FEELS, and how much effort they are having to put into keeping cool.
We know dogs pant to keep cool. And just like the different settings of an air con system, dogs will adapt their panting pattern and intensity to meet their thermoregulatory needs.
Let's look at Digger's panting patterns:
🟢 When he feels cool, he is not panting
🟡 When he feels a little warm, he is panting with a slightly open mouth, barely showing his tongue
🟠 When he feels very warm, he opens his mouth wide and his tongue becomes longer
🔴 When he feels hot, he opens his mouth very wide, his tongue is long, floppy and looks the shape of a paddle (paddle tongue). In some dogs, the tongue may curl up
🟣 When dogs feel too hot and hit their limit of their own cooling capacity, they pant uncontrollably and cannot be disrupted, e.g. with food or a toy.
Panting patterns are a livestream of thermoregulatory information that we can watch carefully, and that we can monitor continuously even when dogs exercising.
When we observe that a dog begins to climb the ladder of more and more intense panting, that progressive change provides us with an early warning system that the dog is starting to feel too hot 🔥 ⚠️
The key message here is very simple, and particularly for those of us who care for high-drive dogs with barely any sense of self-preservation:
Dog begins to feel too hot 🔥
Stop all physical activity immediately ✋️
Cool the dog down 💦 🌳
Monitor panting until the intensity decreases / panting stops
So do I need a thermometer to keep my dogs safe on a hot day? No. Thankfully their Pant-o-meter tells me all I need to know about how cool or warm they feel 👍
