Can Dogs Eat Acorns? – No, They Can’t

When you see acorns scattered across the ground during a walk with your furry friend, it might be tempting to let them nibble on these natural treasures. However, it’s vital to know that the answer to whether dogs can eat acorns is a resounding no. Acorns contain tannins, which can be toxic to dogs and represent a choking hazard. Consumption of acorns by dogs can lead to severe health complications and, in some cases, can be fatal.

Can Puppies Eat Acorns?

For puppies, the situation with acorns is even more critical. The answer remains a solid no. Puppies have a more delicate digestive system and are smaller in size, which means they are even more susceptible to the toxic effects of tannins found in acorns. Not to mention, their curiosity and tendency to chew on things make them more at risk of choking on these small objects.

Why Are Acorns Harmful for Dogs?

Acorns pose a considerable risk for dogs for a few reasons. Here’s a closer look at why these seemingly harmless nuts are dangerous.

Obstruction Risk

Acorns are of a size and shape that could easily be swallowed by a dog. Once ingested, they can cause intestinal blockages, particularly in smaller breeds or puppies. This is a life-threatening emergency that can require surgical intervention.

Tannic Acid

The tannic acid in acorns can cause stomach upset, kidney failure, and even poisoning in dogs. Symptoms of tannic acid poisoning can be severe and should not be taken lightly.

Gastrointestinal Issues

In addition to tannic acid, the hard exterior of acorns can irritate the lining of a dog’s digestive system. This can lead to vomiting, diarrhea, and abdominal pain—common signs of gastrointestinal distress in dogs.

Symptoms to Watch Out For After Dogs Consume Acorns

  • Vomiting: Look for signs of nausea or active vomiting, which can indicate that the dog’s body is trying to expel the acorn.
  • Diarrhea: Frequent loose or watery stools might signal that the acorn has disturbed the digestive system.
  • Lethargy: If your dog seems unusually tired or uninterested in activities they usually enjoy, it might be a symptom of acorn ingestion.

Immediate Steps to Take if Your Dog Eats Acorns

  • Examine: Check inside your dog’s mouth to see if there are any more pieces of acorn that you can safely remove.
  • Call the Vet: Contact your veterinarian immediately for professional advice on handling the situation.
  • Monitor: Keep a close eye on your dog for any signs of distress, and follow your vet’s guidance closely.

Safe Alternatives to Acorns

While acorns are dangerous for dogs, there are safe alternatives that they can enjoy. Consider offering your dog these safer food options instead:

  • Carrots – A crunchy and nutritious snack that’s great for your dog’s teeth.
  • Apples – A sweet treat full of vitamins but remember to remove the seeds and core.
  • Blueberries – High in antioxidants and perfectly sized for a small, healthy snack.


Despite acorns being a common find in nature, they pose significant risks to canines, including gastrointestinal blockage and tannin poisoning. As dog owners, it’s our duty to monitor what our dogs ingest and provide them with safe, dog-friendly alternatives. Always supervise your pets during outdoor activities and keep these unsafe nuts out of their reach. The health and safety of our furry pals depend on our awareness and prompt action.
