Mysterious Summer Illnesses: How to Spot Early Signs of Heatstroke, Dehydration & Overexertion

Ah, summertime in Pennsylvania — long walks at Southpointe, romps through the backyard, weekends by the lake. For pet parents, this season is a chance to make beautiful memories outdoors with their furry companions. But as the sun shines brighter and days grow longer, it’s also a time when some puzzling health issues quietly emerge in our pets. At Akeso Veterinary Clinic, we’re seeing an uptick in visits during the summer for symptoms that aren’t always easy to trace — signs of heatstroke, dehydration, and overexertion that can sometimes masquerade as something else entirely.

While the dangers of leaving a dog in a hot car or walking them during peak temperatures are well-known, many summer-related illnesses aren’t so straightforward. Let’s take a closer look at some of the less obvious early signs and what you can do to protect your pet.

Heatstroke: More Than Just Heavy Panting

Heatstroke can creep in without warning — even on seemingly mild days when humidity is high or your pet gets too excited during play. It’s not always about extreme temperatures; it’s about how your pet’s body handles heat.

Watch For:

– Glazed eyes or anxious behavior during rest
– Excessive drooling, especially from pets who don’t normally drool
– Wobbly gait or uncharacteristic stumbling
– Bright red or very pale gums

What You Can Do:

• Cool them gradually: use lukewarm water on paws and belly (not ice-cold).
• Offer water, but don’t force them to drink.
• Avoid car rides with no AC — even short ones.
• Call your vet immediately if symptoms escalate.

Dehydration: The Silent Summer Threat

Many pets in Canonsburg become dehydrated before their owners even realize it. Unlike humans, dogs and cats don’t sweat, and by the time they show symptoms, they may already be in distress.

Watch For:
– Tacky or sticky gums
– Sunken eyes or lethargy
– Skin that doesn’t quickly return to place after a gentle pinch
– Decreased appetite or unusually small urine output

What You Can Do:

• Add water to kibble or offer chilled low-sodium broth
• Provide shaded areas and fresh water bowls in multiple locations
• Consider electrolyte supplements (safe for pets) — ask your vet first

Overexertion: Not Just a Problem for Senior Pets

We often assume younger pets can go all day — fetch, hike, run — and bounce back easily. But overexertion can lead to delayed fatigue, muscle strain, or even cardiac stress in some breeds.

Watch For:

– Delayed soreness or stiffness a few hours after play
– Slower recovery of breathing post-activity
– Reluctance to jump or climb stairs the next day
– Unusual vocalizations when standing up

What You Can Do:

• Schedule rest breaks during activities — 10 minutes every 30 minutes
• Rotate between play and puzzle toys that stimulate the mind
• Know your breed’s limits — brachycephalic dogs like Frenchies and

• Bulldogs are more prone to overheating and fatigue

Remember: Not All Summer Symptoms Have a Clear Cause

If your pet “just isn’t acting right” — even if the symptoms seem mild — don’t write it off as a one-time fluke. Heat-related illnesses can appear as anything from digestive upset to anxiety-like behavior, and they often build over days.

At Akeso Veterinary Clinic, we believe in proactive care and early intervention. Our team in Canonsburg, PA is here to help you decode those subtle signs before they escalate.
