Summer heat can transform a leisurely walk into a dangerous situation for your canine companion faster than you might realize. Dogs regulate their body temperature differently than humans, relying primarily on panting and limited sweating through their paw pads, making them particularly vulnerable to heat-related emergencies when temperatures soar.

At Mountain View Animal Hospital & Holistic Pet Care, we understand how concerning it can be to worry about your pet’s safety during hot weather. Recognizing the early warning signs of overheating can mean the difference between a manageable situation and a life-threatening emergency that requires immediate veterinary intervention.

1. Excessive Panting and Drooling

Normal panting helps dogs cool themselves, but excessive panting that seems disproportionate to the activity level or temperature may indicate that your dog is struggling to regulate its body temperature. You may notice heavy, rapid breathing that continues even when your dog is resting in a cooler area.

Thick, ropey drool often accompanies this excessive panting. While some drooling is normal, especially in certain breeds, heat-related drooling tends to be more viscous and abundant than usual. Pay attention if the drool appears unusually thick or if your typically non-drooling dog suddenly starts producing excessive saliva.

2. Lethargy and Weakness

A dog experiencing heat exhaustion will often display obvious signs of fatigue and weakness. Your normally energetic pet may seem reluctant to move, appear sluggish, or lie down frequently during activities they usually enjoy. This lethargy differs from normal tiredness after exercise because it persists even with rest.

Some dogs may stumble or seem unsteady on their feet. If your dog appears unusually tired or weak, especially during warm weather, consider this a warning sign that requires immediate attention and cooling measures.

3. Vomiting and Diarrhea

Digestive upset commonly occurs when dogs overheat, as their body systems become stressed from the elevated temperature. Vomiting may start as occasional episodes but can quickly become more frequent and severe if the overheating continues.

Diarrhea may accompany vomiting, and you may notice that the stool appears looser than normal or contains mucus. These digestive symptoms indicate that your dog’s internal systems are under significant stress from the heat.

4. Changes in Gum and Tongue Color

Healthy dogs typically have pink gums and tongues, but overheating can cause noticeable color changes. Gums may appear bright red initially due to increased blood flow as the body attempts to cool itself. As the condition worsens, gums may turn pale, white, or even blue, indicating poor circulation and oxygen flow.

The tongue may also change from its standard pink color to deep red or purple. These color changes in mucous membranes represent serious warning signs that require immediate emergency care.

5. Difficulty Breathing and Heart Rate Changes

Beyond excessive panting, you may notice your dog having genuine difficulty breathing. The breathing may become shallow, rapid, or seem labored even when the dog is at rest. Some dogs may wheeze or make unusual sounds while breathing.

You may also notice changes in your dog’s heart rate if you place your hand on their chest. An elevated or irregular heartbeat often accompanies overheating as the cardiovascular system works harder to circulate blood and regulate temperature.

6. Disorientation and Loss of Coordination

Heat exhaustion affects the nervous system, leading to confusion and disorientation in affected dogs. Your pet may seem lost or confused in familiar environments, fail to respond to their name, or appear to stare blankly into space.

Loss of coordination can be seen through unsteady walking, stumbling, or difficulty standing. Some dogs may walk in circles or bump into objects they would typically avoid. These neurological symptoms indicate severe overheating requiring immediate veterinary care.

When to Seek Immediate Help

If you notice any combination of these signs, begin cooling your dog immediately using lukewarm water and move them to a shaded, air-conditioned area. It’s vital never to use ice-cold water, as this can cause blood vessels to constrict and actually hinder the cooling process.

Contact your veterinarian right away, even if cooling measures seem to help initially. Research from the National Institutes of Health shows that cooling your pet before arrival at the hospital increases their survival chances from 50% to 80%. Heat exhaustion can cause internal damage that may not be immediately apparent. A professional evaluation ensures that your pet receives the appropriate treatment and monitoring they need to recover.
