Can Dogs Get Sick from Rain?
Rainy days can show up without warning, especially during the wetter months. One moment the sky is clear, and the next, you and your pup are caught in a downpour. While a little water might seem harmless, rainy walks can sometimes lead to health issues if your dog stays wet or cold for too long.

Can Dogs Get Sick from Rain?
Yes, dogs can get sick from being in the rain for extended periods. It’s not the rain itself, but the combination of wet fur, cold temperatures, and exposure to bacteria in puddles or on dirty surfaces that increases their risk. Prolonged dampness weakens their immune defenses and can lead to conditions like respiratory infections or skin problems.
What Symptoms Should You Watch For?
After a rainy walk, pay close attention to your dog’s behavior and health. Wet weather can lead to more than just muddy paws—here are the signs that your dog might not be feeling their best:
-
Shivering or Low Energy If your dog starts to shiver even after drying off or seems unusually tired, it may be a sign they're feeling chilled or fighting off a mild case of hypothermia. Smaller breeds and short-haired dogs are especially vulnerable to losing body heat quickly when wet.
-
Coughing or Sneezing Sudden coughing or frequent sneezing can point to kennel cough or another respiratory issue, especially if your dog inhaled cold air or came into contact with contaminated surfaces while out in the rain. These symptoms might start mild but can worsen without attention.

Itchy or Irritated Skin Prolonged dampness, especially if your dog stayed wet for a while, can cause skin discomfort. You may notice your dog scratching more than usual, licking their paws excessively, or developing redness or bumps on their belly, ears, or between their toes.
-
Loss of Appetite or Sluggish Behavior A dog who seems uninterested in food or less playful than usual might be under the weather. While this can result from many factors, a sudden change in energy levels after a rainy outing may signal that your dog caught a chill or picked up an infection.
How to Prevent Rain-Related Illness
Protecting your pup from the effects of rainy weather doesn’t require much—just a few smart steps can go a long way in keeping them healthy and dry:
-
Dry Them Off Thoroughly After Every Walk Always towel-dry your dog as soon as you get home, paying close attention to areas that stay wet the longest—like the paws, belly, underarms, and behind the ears. Leaving these spots damp can cause skin issues or make your dog feel chilled indoors.
-
Invest in a High-Quality Dog Raincoat A waterproof raincoat isn’t just a fashion statement—it’s your dog’s first line of defense against wet and chilly conditions. Choose one with full belly coverage, adjustable straps, and a hood or collar to keep water out. Reflective strips are a great bonus for visibility during cloudy or dark walks.

Avoid Puddles and Muddy Areas Puddles might look harmless, but they can contain bacteria, parasites, or chemicals like antifreeze and lawn treatments. Guide your dog around wet, dirty spots and rinse off any mud or contaminants on their paws right after your walk.
-
Limit Outdoor Time in Harsh Conditions When it’s pouring or windy, keep walks brief and purposeful—just enough for bathroom breaks and a bit of fresh air. Replace longer outdoor activities with indoor games like fetch, tug-of-war, or treat puzzles to keep them stimulated without the chill.
-
Keep Them Warm Indoors, Too After drying off, make sure your dog stays warm indoors. A cozy sweater or soft pajamas can help regulate body temperature, especially for senior dogs, puppies, or breeds more sensitive to cold.
A Little Rain Doesn’t Have to Mean Trouble
With the right precautions, rainy walks can still be part of your dog’s routine. Stay prepared with proper gear, keep your pup dry, and be on the lookout for any changes in behavior. A little planning goes a long way in keeping those tails wagging—rain or shine.
