Is It Too Hot or Too Cold for Your Dog? A Temperature Safety Guide
Knowing the safe temperatures for dogs can mean the difference between a fun outdoor adventure and a life-threatening emergency. But how do you tell if it’s too hot or too cold for your pup?
Every dog handles weather differently, but key factors like breed, size, age, coat type, and health conditions determine their comfort zone. For example:
- Small dogs and seniors with thin coats struggle in cold weather and may need sweaters or indoor warmth.
- Large or double-coated breeds (like Huskies) tolerate cold better but overheat easily in summer.
- Brachycephalic dogs (Pugs, Bulldogs) and overweight pets face higher heatstroke risks even in mild warmth.
Extreme temperatures demand extra caution:
Cold weather dangers: Hypothermia, frostbite (especially for short-haired breeds in wet conditions).
Hot weather risks: Heatstroke (often fatal for thick-coated or short-snouted dogs without shade/water).
Our Dog Comfort Scale infographic (below) breaks down temperature safety by size, so you can quickly assess risks. Plus, learn how to adjust for your dog’s unique needs—because their safety starts with your awareness.
Hypothermia in Dogs: Signs, Risks, and Emergency Response
Hypothermia isn’t just discomfort—it’s a life-threatening emergency that strikes when a dog’s body temperature plummets below normal (typically under 99°F/37.2°C). Without prompt care, it can cause organ failure, coma, or even death.
Which Dogs Are Most at Risk?
- Small breeds (Chihuahuas, Toy Poodles) and short-haired dogs (Greyhounds, Boxers).
- Senior dogs or puppies with underdeveloped temperature regulation.
- Wet or damp dogs (water accelerates heat loss).
Critical Warning Signs
✔️ Early Stage: Violent shivering, slow movements, cold ears/paws.
✔️ Advanced Stage:
- Weak pulse, shallow breathing
- Glassy-eyed stare (fixed pupils)
- Muscle stiffness or collapse
- Unconsciousness (coma)
What to Do IMMEDIATELY
- Move Indoors: Get your dog out of the cold fast.
- Warm Gradually:
- Wrap them in dry blankets/towels (avoid direct heat like heating pads, which can burn).
- Use your body heat by holding them close.
- Call Your Vet: Even if symptoms improve—hidden organ damage can occur.
Never ignore shivering or lethargy in cold weather! Hypothermia worsens rapidly, especially in high-risk dogs.
Heatstroke in Dogs: Life-Threatening Signs & Emergency Cooling
Hot weather turns deadly fast for dogs—they can’t sweat like humans, and heatstroke kills within minutes. Recognize these critical symptoms before it’s too late:
🚨 Emergency Red Flags
✔️ Early Signs:
- Heavy panting, thick drooling
- Bright red gums/tongue
- Racing heartbeat
✔️ Progressing to Crisis:
- Vomiting (especially with blood)
- Stumbling or disorientation
- Muscle tremors/seizures
- Collapse or unconsciousness
Act FAST—Here’s How
- Move to Shade/Cool Area
- Carry them if possible (exercise worsens overheating).
- Cool Gradually
- Wet towels on paws, groin, and neck (avoid ice or cold water—shock risk!).
- Offer small sips of cool (not icy) water.
- Call the Vet Immediately
- Even if your dog seems better—internal damage can be hidden.
⚠️ High-Risk Dogs:
- Brachycephalic breeds (Pugs, Bulldogs)
- Thick-coated (Huskies, Malamutes)
- Overweight or senior dogs

25 Lifesaving Ways to Keep Your Dog Cool in Hot Weather
Hydration & Treats
- Ice-cold hydration: Offer fresh water with ice cubes—add broth for picky drinkers.
- Frozen fruit pops: Blend dog-safe fruits (blueberries, watermelon) and freeze in molds.
- Portable water: Carry a collapsible bowl on walks.
Beat the Heat Outdoors
- Walk smart: Go out before 8 AM or after 7 PM to avoid scorching pavement.
- Paw protection: Test asphalt with your hand—if it’s too hot for you, it burns paws.
- DIY shade: Use a pop-up tent or umbrella in your yard.
- Kiddie pool time: Just 2 inches of water lets them splash safely.
Cooling Gear & Hacks
- Cooling vest: Soak in water for evaporative cooling (great for hikes).
- Chilled towels: Drape wet towels over their belly/armpits—re-wet every 10 mins.
- Frozen Kongs: Stuff with peanut butter and freeze for hours of cool fun.
- Elevated cot bed: Lets air circulate underneath (vs. heat-trapping mats).
Home Cooling Strategies
- Fan + ice hack: Place a bowl of ice in front of a fan for DIY AC.
- Tile retreat: Encourage naps on bathroom tiles (naturally cooler).
- Blackout curtains: Block sun to keep indoor temps down.
Emergency Signs & Prevention
- Heatstroke 911: Glassy eyes, vomiting, or stumbling? Cool them gradually and call the vet.
- Car = death trap: Even 70°F outside can turn a car into 100°F in minutes.
- Grooming don’ts: Never shave double-coated breeds—their fur insulates against heat.
Play It Safe
- Swap fetch for puzzles: Mental games tire them out without overheating.
- Sunscreen musts: Protect pink noses and thin fur with pet-safe SPF.
- Frozen bottle buddy: Freeze water bottles for them to lean against.
Proactive Care
- Weigh risks: Overweight/senior dogs overheat faster—adjust activities.
- Know your breed: Bulldogs/Pugs need AC; Huskies prefer shade over snow.
- Tech help: Use a pet thermometer to monitor indoor/outdoor temps.
When to Act Fast
- Vet on speed dial: Save your vet’s emergency number in your phone.
- Cool, don’t shock: Never use ice baths—lukewarm water prevents shock.
5 Dangerous Cooling Myths Every Dog Owner Must Stop Believing
❌ Myth 1: “Shaving My Dog Will Keep Them Cooler”
Truth: Double-coated breeds (Huskies, Golden Retrievers) rely on their undercoat for insulation—shaving disrupts their natural temperature regulation and increases sunburn risk.
✅ Do this instead: Regular brushing to remove dead underfur.
❌ Myth 2: “Dogs Can’t Get Sunburned”
Truth: Short-haired, light-colored, and hairless dogs (e.g., Dalmatians, Xolos) are prone to sunburn on noses, ears, and bellies.
✅ Do this instead: Apply pet-safe sunscreen (zinc-free!) to vulnerable areas.
❌ Myth 3: “Ice Water Prevents Heatstroke”
Truth: Ice-cold water can cause shock. Dogs with heatstroke need cool (not frigid) water and vet care.
✅ Do this instead: Offer room-temperature water first, then small sips of cool water.
❌ Myth 4: “If My Dog Stops Panting, They’re Fine”
Truth: Sudden silence during overheating is a red flag—it may mean they’re collapsing from exhaustion.
✅ Do this instead: Check for bright red gums, vomiting, or stumbling.
❌ Myth 5: “Parked Cars Are Safe if the Windows Are Cracked”
Truth: Even with windows open, a car’s interior can reach fatal temperatures in 10 minutes.
✅ Do this instead: Leave your dog at home on hot days—no exceptions.
Final Thoughts: Keeping Your Dog Safe in Extreme Temperatures
Whether battling winter chills or summer heat, your dog’s safety hinges on prevention, awareness, and quick action. Remember:
- Cold weather risks: Small breeds, seniors, and short-haired dogs can slip into hypothermia (shivering, lethargy) in minutes. Always provide a warm shelter or insulated jacket below 32°F (0°C).
- Hot weather dangers: Brachycephalic and thick-coated dogs overheat fast. Pavement burns at 85°F (29°C), and heatstroke kills in under 10 minutes.
Your action plan:
✔️ Know the limits: Use our [Dog Comfort Scale Infographic] as your go-to guide.
✔️ Spot early signs: Glassy eyes? Excessive panting? Weakness? Intervene immediately.
✔️ When in doubt, call your vet: Temperature extremes can cause hidden organ damage.
