As the temperatures drop and the crisp air of fall rolls in, many dog owners and their pets are eager to spend more time outdoors. Cooler weather can be a refreshing change from the heat of summer, but it also brings unique challenges for your dog’s health, safety, and comfort. With a few simple precautions, you can ensure your four-legged friend enjoys the season safely.
Don’t Skip Heartworm and Flea Prevention
While many people associate pests like mosquitoes and fleas with summer, they remain active well into fall in many regions. Stopping your pet’s parasite prevention too early can put them at serious risk.
“Even though the temperatures are starting to fall, mosquitoes are still a threat, so don’t stop using your heartworm and flea prevention.”
— Dr. Bev Unger, DVM, VCA Angel Clinic, Flower Mound, Texas
Heartworm disease, transmitted by mosquitoes, can be life-threatening for dogs, and fleas can lead to discomfort, allergic reactions, and tapeworms. Continue your dog’s monthly heartworm, flea, and tick prevention year-round unless your veterinarian advises otherwise.
Ease into Outdoor Exercise
Fall is a fantastic time to get moving with your dog—cooler temperatures are often safer and more enjoyable for pets than summer heat. However, it’s important to reintroduce activity safely, especially if your dog hasn’t been active recently.
“When the temperatures start to drop and the Fall days arrive walking your dog is a great exercise for you and your pet. But remember if you have not been in a routine exercise mode, start slowly and gradually increase your walking distance for you and your pets health.”
— Dr. Bev Unger, DVM, VCA Angel Clinic, Flower Mound, Texas
Start with short walks and build up gradually to prevent muscle strain or fatigue. Senior dogs, puppies, and overweight pets especially benefit from a slow, thoughtful return to exercise.
Watch for Cold Weather Risks
Even in early fall, temperatures can swing dramatically. Monitor your dog for signs they may be too cold—shivering, whining, lifting paws, or seeking shelter. Short-haired breeds, small dogs, and seniors may need a light sweater during chilly mornings or evenings.
Protect Their Paws
Wet, cold ground and rough terrain can lead to cracked or irritated paw pads. Consider using dog-safe balms to protect paws before walks and wipe your dog’s feet afterward to remove moisture, debris, and potential chemicals like lawn treatments.
Adjust Nutrition if Needed
If your dog becomes more active during cooler months, they may need a slight increase in calories. On the other hand, if activity decreases, maintaining a healthy weight may require reducing portions. Consult your veterinarian for personalized nutrition advice.
Maintain Comfort Indoors
As outdoor temperatures fall, make sure your dog has a warm, dry place to sleep. Avoid letting them rest on cold floors—use a raised bed or soft blanket to protect their joints and keep them comfortable.
Final Thoughts
With a little preparation, fall can be one of the best seasons to enjoy with your dog. By maintaining parasite prevention, easing into exercise, and protecting against cold weather risks, you’ll support your dog’s health and happiness all season long.
If you ever have questions about your pet’s seasonal care, your veterinarian is your best resource. A little proactive attention now can prevent bigger problems later—and help your dog enjoy every tail-wagging adventure this fall!
