How Hot is Too Hot for Dogs? Keep Your Pet Safe This Summer in Montgomery & Hillsborough NJ

As the warm weather returns to Montgomery and Hillsborough Township, NJ, many pet parents are eager to get outside and enjoy the sunshine with their dogs. However, it’s important to remember that while you may love the heat, dogs are far more vulnerable to high temperatures—especially in the humid summers of Central New Jersey.

At The Modern Canine, we prioritize pet wellness, and that means helping local dog owners understand the risks of heat-related illnesses and how to keep their furry companions safe during spring and summer.

Do Dogs Overheat in Warm Weather?

Yes, dogs can easily become overheated in the warmer months. Unlike humans, dogs don't sweat efficiently. They can only sweat through their paw pads and primarily regulate heat by panting—a method that becomes far less effective in humid weather, which is common in Montgomery and Hillsborough.

Here are a few common reasons dogs overheat:

  • Breed sensitivity: Brachycephalic breeds (short-nosed dogs like Pugs, Bulldogs, Boxers, and Shih Tzus) are at higher risk because they can't pant effectively.

  • Long outdoor exposure: Spending extended time outside in hot, humid conditions without shade or breaks.

  • Lack of airflow: Being left in a hot car or poorly ventilated area.

  • Dehydration: Limited access to fresh, clean water.

  • Health conditions: Dogs with heart disease, obesity, or respiratory issues are more susceptible to heat stress.

  • Coat type: Thick or double-coated breeds (e.g., Golden Retrievers) retain more heat than short-haired dogs.

  • Coat color: Darker coats absorb more heat from the sun.

  • Age & size: Young puppies, senior dogs, and large breeds struggle more with heat regulation.

What Temperatures Are Unsafe for Dogs in Central NJ?

A dog’s normal body temperature ranges from 100.5°F to 102.5°F. Once a dog’s body temperature reaches 106°F, they’re in the danger zone for heatstroke, which can be fatal within minutes.

In Montgomery and Hillsborough, high humidity combined with temperatures above 70°F can already pose a risk, especially for certain breeds. On days where temps hit 80–90°F, you should:

  • Limit your dog’s outdoor activity.

  • Take short leashed walks for bathroom breaks only.

  • Always carry water.

  • Avoid walking on hot pavement that can burn paws.

Heatstroke Symptoms to Watch For

If you're walking your dog around local parks or neighborhoods in Montgomery Township or Hillsborough, keep an eye out for these signs of overheating:

  • Excessive panting or drooling

  • Lethargy or confusion

  • Vomiting or diarrhea

  • Bright red gums or tongue

  • Collapse or unresponsiveness

If you suspect heatstroke, get your dog into a cool, shaded area immediately and contact your veterinarian or a local emergency vet clinic.

Hot Weather Dog Safety Tips from The Modern Canine

  • Walk your dog early in the morning or after sunset to avoid peak heat.

  • Use cooling vests or mats during outdoor activities.

  • Provide shaded areas and constant access to water in your yard.

  • Avoid long car rides unless the vehicle is well air-conditioned.

  • Groom your dog regularly to remove excess undercoat, but don’t shave double-coated breeds.
