Cooler air. Colourful leaves. Cozy neighbourhood walks.
Fall might be one of the best seasons to get outside with your dog, but it also comes with a few hidden hazards that are easy to miss. From mushrooms on the trail to Halloween candy at home, a little awareness can help keep your pup safe while still enjoying every crisp, golden walk together.
Here are eight fall hazards every dog parent should know before heading into the season.
Around the House & Garage
These are some of the highest-risk fall hazards because they are often found close to home.
1. Antifreeze
As temperatures drop, antifreeze becomes more common in garages, driveways, and parking lots. Many antifreeze products contain ethylene glycol, which can taste sweet to pets and is highly toxic, even in small amounts.
Keep antifreeze locked away, clean up spills right away, and be mindful of puddles near cars. If your dog walks through an unknown spill, wipe their paws before they have a chance to lick them.
If you think your dog may have ingested antifreeze, contact your veterinarian or an emergency animal hospital immediately.
2. Halloween Candy
Halloween candy is fun for people, but it can be risky for dogs.
Chocolate can be dangerous, and xylitol, sometimes labelled as birch sugar, is toxic to dogs. Candy wrappers, lollipop sticks, and small packaging pieces can also become choking or blockage risks.
Keep candy bowls high, sealed, and away from curious noses. It also helps to remind children and guests not to share candy with the family pup, even as a “small treat.”
3. Candles & Fall Decor
Candles, string lights, mini pumpkins, potpourri, and seasonal decorations make a home feel cozy, but curious dogs may see them as something to chew, sniff, or knock over.
Keep open flames out of reach and never leave them unattended. Tuck cords away, avoid placing small decor pieces where your dog can grab them, and move anything breakable to a safe spot.
A cozy home is even better when it is pup-safe, too.
Out on the Walk
Fall walks are beautiful, but this is where dogs often come across seasonal hazards before we notice them.
4. Wild Mushrooms
Fall is prime mushroom season, especially on damp trails, wooded paths, and shaded lawns.
Some wild mushrooms are toxic, and it can be very difficult to tell safe mushrooms from dangerous ones by sight. The safest approach is simple: do not let your dog eat any wild mushrooms.
Use a shorter leash in wooded or damp areas, keep an eye on what your dog is sniffing, and practise a strong “leave it” cue before you need it.
5. Acorns & Fallen Nuts
Acorns and fallen nuts are everywhere in autumn. While one curious sniff is usually not the issue, eating them can cause problems.
Acorns contain tannins that may upset a dog’s stomach. Whole acorns and nuts can also become choking hazards or cause intestinal blockages, especially if eaten in quantity.
If your regular walking route is covered, keep your pup moving and reward them for leaving things on the ground.
6. Fallen & Fermented Fruit
Windfall apples, pears, and other fruit can ferment quickly once they sit on the ground.
Spoiled fruit may cause vomiting or diarrhea, and fruit pits can be choking hazards. Some pits can also cause digestive concerns depending on the fruit and amount eaten.
If you have fruit trees in your yard, do a quick sweep before letting your dog out. Think of it as keeping the backyard from turning into a fall snack buffet.
7. Mouldy Leaves, Pumpkins & Gourds
Dogs love leaf piles, but old damp leaves can grow mould. The same goes for decorative pumpkins and gourds that sit outside too long.
Plain, properly prepared pumpkin can be fine for many dogs, but mouldy or rotting pumpkins should never be eaten.
Compost old leaves, pumpkins, and gourds somewhere your dog cannot reach. If your pup loves diving into leaf piles, choose fresh, dry piles and supervise closely.
8. Fleas & Ticks Do Not Clock Out in Fall
It is easy to think flea and tick season ends when summer does, but ticks can stay active into fall when temperatures are above freezing and there is no snow cover.
After walks through tall grass, wooded paths, or leaf-covered trails, do a quick tick check. Pay close attention to the ears, armpits, between the toes, under the collar, and around the tail.
Continue your vet-recommended parasite prevention for as long as your veterinarian advises for your area.
Keep Your Fall Adventures Safe
You do not need to avoid the outdoors. Fall is too beautiful for that.
A little preparation can make your autumn walks safer, easier, and more enjoyable.
Before your next fall adventure:
✔ Keep antifreeze locked away and clean up spills right away
✔ Store chocolate, xylitol or birch sugar candy, and wrappers out of reach
✔ Use a shorter leash around mushrooms, acorns, and fallen fruit
✔ Compost mouldy leaves, pumpkins, and gourds where dogs cannot reach them
✔ Do a full-body tick check after wooded or grassy walks
✔ Add reflective gear for darker morning and evening walks
✔ Keep candles, cords, and small decor out of chew-range
The goal is not to worry through the season. It is to feel prepared, so you and your dog can enjoy every crisp walk, colourful trail, and cozy evening together.

Frequently Asked Questions
Are ticks still active in the fall?
Yes. Ticks can still be active in fall, especially when temperatures are above freezing and the ground is not covered in snow. It is a good idea to check your dog after walks through grass, trails, and wooded areas.
Is pumpkin safe for dogs?
Plain, properly prepared pumpkin may be safe for many dogs, but mouldy, rotting, sweetened, or spiced pumpkin should be avoided. Decorative pumpkins left outside should be composted where dogs cannot reach them.
What should I do if my dog eats Halloween candy?
Call your veterinarian, an emergency animal hospital, or a pet poison-control service right away. Try to have the candy packaging, ingredients, estimated amount eaten, and your dog’s weight ready.
Can dogs eat wild mushrooms?
Dogs should not eat wild mushrooms. Some can be toxic, and it is very difficult to identify safe mushrooms by sight. Prevent your dog from eating mushrooms on walks and contact a veterinarian if ingestion happens.
What should I carry on fall walks?
A leash, waste bags, water, treats for recall or “leave it” practice, reflective gear for low-light walks, and your vet’s contact information are all helpful items to have during fall adventures.
Final Thought
Fall is made for slow walks, crunchy leaves, and little adventures with your best friend by your side.
