Central Florida’s climate asks more of dogs than most parts of the country. Heat alone is one thing, but Lake Mary, Sanford, and Longwood combine high temperatures with the kind of humidity that makes a dog’s primary cooling method (panting) far less effective than it would be somewhere drier. Dog walks that would be completely fine in a low-humidity climate can be a lot more dangerous here than they may be in other areas of the country.
As pet owners and dog sitters, we need to recognize these issues as soon as possible, especially during summer. Dogs move through distinct stages once they start overheating, and catching it early is a lot easier to manage than catching it late.
The Central Florida Heat is Different and Dangerous
We already have to worry about dogs in the heat simply because pavement can heat up so severely, it can burn a dog’s feet. If you cannot put your own hand on the pavement, your dog’s paws are burning on it.
That can burn your dog’s paws. But what we are worried most about is something more dangerous: overheating. Dogs cool themselves primarily through panting. Panting moves air over the moist surfaces of their tongue and airway to release heat.
But this process works best in dry air.
In the kind of humidity that’s typical across Lake Mary, Sanford, and Longwood, the surrounding air is already saturated with moisture, which slows down how effectively that panting actually cools a dog down. Dogs only know how to pant, and have no alternative method that may help them cool – or even let you know that their panting is not working.
The Earliest Signs of Heat Stress
The earliest stage of overheating is called heat stress. It is also the easiest to miss, since some of these signs can look like normal dog behavior at first glance:
- Heavier Panting Than Usual — Panting that’s faster or more labored than what’s typical for that specific dog, especially early in a walk rather than after real exertion.
- Excessive Drooling — More saliva than normal, sometimes thick or stringy.
- Bright Red Gums or Tongue — A dog’s body pushes extra blood to the extremities as it tries to release heat, which can turn gums and tongue a noticeably brighter red.
- Restlessness — Pacing, repeatedly lying down and getting back up, or general difficulty settling, which often reflects a dog trying to find a cooler position.
- Seeking Shade or Cool Surfaces — A dog that suddenly wants to lie on tile, concrete in the shade, or anywhere cooler than where it currently is.
Any one of these is a signal your dog is finding the heat overwhelming. If you start noticing several of these together, especially in a dog that’s normally comfortable outside, is a clear signal to get them somewhere cooler right away.
Heat Stress Typically Progresses to Heat Exhaustion
If those early signs go unaddressed, a dog can move into heat exhaustion, a more serious stage marked by heavier panting and drooling, noticeable lethargy, and a genuine reluctance to keep moving. You may notice that your dog was excited for a walk originally, but now wants to stop or lie down.
Weakness is often part of this stage too, showing up as unsteady movement or a dog that seems less coordinated than usual. This is the point to stop the activity entirely and get a dog into shade or air conditioning, with cool water available.
When It Becomes a Heatstroke Emergency
Heatstroke is the most serious stage. This is when it has already progressed beyond normal heat and requires immediate veterinary attention rather than home management. It involves vomiting or diarrhea, stumbling or apparent disorientation, collapse, seizures, and gums turning pale. These are all signs the dog is struggling to function.
This progression can happen fast, sometimes within minutes once a dog moves from exhaustion into true heatstroke. This is why it is so important to catch the earlier signs.
Dogs at Higher Risk in This Climate
Heat stroke can affect all dogs in our weather, because it is hotter and more humid than most other places in the world. However, some dogs handle Central Florida’s heat and humidity worse than others. For example:
- Flat-Faced Breeds — Bulldogs, pugs, and other brachycephalic breeds have airways that already restrict airflow, making panting a less effective cooling tool even in mild heat.
- Senior Dogs and Puppies — Both groups regulate body temperature less efficiently than a healthy adult dog.
- Overweight Dogs — Extra weight makes it harder for a dog’s body to release heat efficiently.
- Thick or Double-Coated Breeds — Heavier coats trap heat close to the body, even in breeds built for colder climates originally.
Most healthy adult dogs handle temperatures up to around 70 degrees comfortably. Dogs in any of these higher-risk groups can start struggling well before that.
How FurBabies Accounts for Florida’s Heat
Every walk and visit scheduled through FurBabies takes Central Florida’s climate into account, from timing walks earlier or later in the day during the hottest months to sitters who know what to watch for once they’re out with a dog. Because every visit gets a detailed update with notes and photos, owners have real visibility into how a dog handled the heat that day, not just a confirmation that the visit happened.
FurBabies Home Pet Care provides dog walking, pet sitting, and in-home care throughout Lake Mary, Sanford, and Longwood, with sitters trained to recognize heat stress before it becomes something more serious. Call 407-489-9418 or set up a free in-home consultation to talk through what your dog needs this summer.
