Fall in Apple Valley: A Field Guide to Acorns, Mushrooms, and Other Things Your Dog Will Eat Anyway

Fall brings acorns, mushrooms and other tempting hazards. Learn what Apple Valley dog owners should watch for on walks and in the yard.

Welcome to Fall: Nature’s All-You-Can-Eat Buffet

Unfortunately, your dog sees it less as a beautiful seasonal landscape and more as an enormous buffet that someone has thoughtfully scattered across the ground.

Acorns? Delicious, apparently.

Mushrooms? Absolutely worth investigating.

Some unidentified object underneath a pile of leaves? Obviously edible. Why else would nature have put it there?

Dogs explore their environment with their mouths, and autumn creates plenty of opportunities for them to encounter things that aren’t particularly interested in becoming lunch.

Acorns: Cute Little Nuts, Big Problem

Oak trees dropping acorns is normal.

Your dog eating them is not something you should encourage.

Acorns contain tannins, which can be harmful to dogs. According to the American Kennel Club, ingestion can cause gastrointestinal upset and, in serious cases, kidney problems. Whole acorns can also create choking or intestinal obstruction concerns.

What should you do?

If your dog routinely hoovers up acorns during walks, prevention is easier than trying to negotiate with a Labrador who has already swallowed one.

Try:

  • Walking around areas with heavy acorn coverage.
  • Keeping your dog on leash in high-risk areas.
  • Practicing a reliable “leave it.”
  • Using “drop it” when necessary.
  • Supervising dogs closely in yards with oak trees.

And remember: “He only ate one” isn’t necessarily a reason to ignore it. If you know your dog swallowed an acorn, contact your veterinarian for advice.

Mushrooms: Don’t Play Amateur MycologistDog approaching a mushroom in the woods

Fall is prime mushroom season, particularly after wet weather.

The problem isn’t that every mushroom is poisonous.

The problem is that some are, and identifying mushrooms accurately can be extremely difficult.

The ASPCA notes that toxic mushrooms can cause gastrointestinal problems, neurological symptoms, liver or kidney damage, seizures and, in severe cases, death.

Pet Poison Helpline similarly advises treating mushroom ingestion seriously because dangerous species can be difficult to distinguish from harmless ones.

The rule is simple

If mushrooms are growing in your yard, remove them before letting your dog roam.

If you’re hiking or walking somewhere mushrooms are present, keep your dog from eating them.

If your dog eats one, don’t wait to see what happens.

Contact your veterinarian or a pet poison service promptly.

And if possible, take photographs of the mushroom and the surrounding area. Don’t rely on a random internet mushroom group to diagnose your dog’s lunch. This is not the time to discover whether your photography skills are good enough for forensic mycology.

Leaves Are Less Exciting—Usually

A mouthful of ordinary fallen leaves isn’t automatically a poisoning emergency.

But the bigger issue is what might be hiding underneath them.

Leaf piles can conceal:

  • Mushrooms
  • Acorns
  • Animal feces
  • Trash
  • Sharp objects
  • Decaying food
  • Dead wildlife
  • Rodent bait

That means “go ahead and eat the entire leaf pile” probably isn’t the enrichment activity we’d recommend.

Compost and Yard Waste Deserve Attention Too

Autumn yard cleanup creates another potential hazard: compost and piles of discarded plant material.

Dogs are opportunistic scavengers. Compost can contain spoiled foods, mold and other materials that can cause illness.

Keep compost bins securely closed and make sure your dog can’t access piles of yard waste that may contain unknown materials.

This is particularly important for dogs who believe the phrase “leave it” is merely a suggestion.black mixed breed dog laying in fall leaves holding stick in mouth

A Better Fall Walk

You don’t need to spend your entire walk staring at the sidewalk like you’re defusing a bomb.

Instead, build a few habits into your normal routine.

Scan ahead

Look at the path in front of you and redirect your dog before they reach something questionable.

Practice “leave it”

This is one of the most useful skills a dog can learn.

Start indoors with something boring and gradually practice around increasingly tempting distractions.

Bring appropriate treats

Reward your dog for checking in with you rather than investigating every piece of sidewalk debris.

Use a leash when necessary

If your dog has a history of eating anything remotely chewable, off-leash freedom may need to wait until you’re in a genuinely safe environment.

What If Your Dog Eats Something Suspicious?

Don’t rely solely on whether your dog looks normal.

Some toxins cause symptoms quickly. Others can take hours to appear.

If you know your dog has swallowed something potentially toxic:

  1. Remove access to the substance.
  2. Save the packaging or material if available.
  3. Photograph an unknown plant, mushroom or object.
  4. Note approximately how much was eaten.
  5. Contact your veterinarian or a pet poison service.
  6. Follow their instructions rather than attempting home remedies.

Do not induce vomiting unless a veterinary professional specifically tells you to do so.

Fall Is Supposed to Be Fun

Fall is one of the best seasons for walking, exploring and enjoying the outdoors. Just remember that your dog’s definition of “interesting” may include things that should remain firmly outside the digestive system.

A little supervision goes a long way.

And if your dog is the type who considers every acorn a personal challenge, every mushroom a tasting opportunity and every leaf pile a five-star restaurant, we’re not judging.
