Can Dogs Eat Pecans? Risks, Pecan Pie, and What to Do

Pecans are everywhere in the fall. They show up in pecan pie on the Thanksgiving table, in candied nut bowls at holiday parties, and in some yards they literally drop from the trees onto the grass. If your dog has a habit of sniffing out anything that hits the floor, it is worth knowing whether pecans are a problem before the holiday baking starts.

The short answer: dogs should not eat pecans. One or two pieces are unlikely to cause a major problem, but pecans are high in fat, can carry dangerous molds, and are a choking and blockage risk, so they do not belong in your dog’s bowl. Here is what veterinary and pet health sources say, what symptoms to watch for, and what to do if your dog gets into the nut dish.

Can Dogs Eat Pecans?

No. The American Kennel Club is clear on this one. Dr. Jerry Klein, the AKC’s Chief Veterinarian, says that though pecans are harmless to humans, they should not be given to dogs. The AKC adds that even a small number of these nuts can make a dog very sick.

Sources do describe the risk a little differently. The AKC calls pecans toxic to dogs because they contain a compound called juglone, the same compound found in walnuts. PetMD says pecans are not toxic in themselves, but that they are hard for dogs to digest and can cause health problems if a dog eats too many. Both sources land in the same place: pecans are not a safe snack for your dog, and you should keep them out of reach.

The ASPCA also lists nuts, including almonds, pecans, and walnuts, among the people foods to avoid feeding pets, because their high amounts of oils and fats can cause vomiting, diarrhea, and potentially pancreatitis.

Why Pecans Are Bad for Dogs

1. They are high in fat

PetMD explains that pecans are high in fat and can lead to stomach upset, including vomiting and diarrhea, if a dog eats too many. Too much fat can also trigger pancreatitis, which PetMD describes as a painful and potentially fatal condition. The AKC lists vomiting, diarrhea, loss of appetite, and lethargy as signs of pancreatitis and says dogs with suspected pancreatitis need immediate veterinary care because they can get very sick quickly and become dehydrated.

2. They can carry dangerous molds

This is the risk many owners do not know about. According to the AKC, pecans and walnuts are very susceptible to growing a mold that contains mycotoxins, and dogs that ingest these mycotoxins can experience tremors, seizures, and other neurological problems. Dr. Klein also notes that pecans can develop aflatoxin, which is produced by a mold called Aspergillus that grows on pecan shells. PetMD agrees that moldy pecans are rare but serious, and can cause severe tremors and seizures.

Even fresh-looking pecans are not a guarantee. The AKC points out that you still run the risk of exposing your dog to harmful mold with fresh nuts.

3. Juglone

The AKC says juglone is found naturally in every part of the pecan and can cause digestive issues if eaten. Dogs that eat pecans are likely to experience vomiting from it, and it may also cause diarrhea.

4. Choking and blockages

Pecans are small and hard, and the AKC notes that their size makes them a possible choking hazard. PetMD adds that pecans still in their shells can be a choking risk if swallowed whole and may cause an obstruction in the digestive system. If you live near a pecan tree, PetMD recommends making sure your dog does not gobble up nuts from the ground, since fallen nuts can also be moldy.

Can Dogs Eat Pecan Pie?

No. PetMD says pecan pie is not safe for dogs. On top of the high-fat pecans, pie is loaded with sugar, corn syrup, and butter, which your dog should not eat. This is one of the easiest Thanksgiving mistakes to make, because a slice left on a low coffee table or a plate scraped into a reachable trash can is an easy target. If you are planning your holiday menu, our guides on whether dogs can eat turkey and whether dogs can eat sweet potatoes cover which parts of the meal are safer to share.

Also watch out for other pecan treats such as candied pecans, pralines, and pecan cookies. These usually add sugar, butter, and sometimes chocolate. Chocolate brings its own serious risks, which we explain in our guide to why dogs can’t eat chocolate.

My Dog Ate a Pecan. What Should I Do?

First, do not panic. Dr. Klein told the AKC that if a dog eats only one or two pieces of pecan, chances are there should not be a major problem. PetMD agrees that a pecan dropped on the floor while you are baking is unlikely to hurt your dog, as long as they do not show signs of illness.

That said, here is a simple plan:

1. Remove any remaining nuts and figure out roughly how many your dog ate, and whether they were shelled, in the shell, moldy, or part of a pie or candy.
2. Check for other ingredients. Chocolate, raisins, or sugar-free sweeteners in a baked good change the picture completely.
3. Call for advice. The AKC recommends contacting a veterinarian right away if your dog eats pecans, even a small amount, and going to an emergency clinic if your regular vet is closed. You can also call the Pet Poison Helpline at (855) 764-7661 or the ASPCA Animal Poison Control Center at (888) 426-4435.
4. Get care right away if the pecans were moldy or your dog shows any symptoms. PetMD says prompt treatment may be needed to prevent serious complications.

Symptoms to Watch For

PetMD lists these signs to watch for after a dog eats pecans:

• Vomiting
• Diarrhea
• Loss of appetite
• Lethargy
• Stumbling or lack of coordination
• Tremors or seizures

Tremors, seizures, or stumbling are especially concerning because they can point to mycotoxins from moldy nuts. Treat those as an emergency.

Can a Dog Die From Eating Pecans?

PetMD says it is not likely that a dog will die from eating pecans, but it is still something to take seriously. Eating a large amount can cause pancreatitis, which can be life-threatening, and moldy pecans can cause severe neurological signs. The safest approach is to keep pecans, pecan pie, and the holiday nut bowl well out of your dog’s reach.

Safer Treats to Share Instead

If your dog is begging while you snack, there are better options. PetMD notes that some nuts, such as plain unsalted peanuts and peanut butter without xylitol, are OK for dogs in moderation, while also reminding owners that what is fine for one dog might not be good for yours, so check with your vet before adding new foods. Many owners find it easier to skip nuts entirely and offer a dog-safe treat or a small piece of plain cooked pumpkin instead. Our guide on whether dogs can eat pumpkin explains how to serve it safely.

Holiday baking spices deserve a look too. If you are making pecan pie, you may also be wondering about the cinnamon in it, which we cover in can dogs eat cinnamon.

Frequently Asked Questions

Are pecans toxic to dogs?

Sources differ on the word. The AKC calls pecans toxic because of a compound called juglone and the molds they can carry, while PetMD says pecans are not toxic but are hard to digest and risky. Either way, both say dogs should not eat them.

How many pecans can make a dog sick?

There is no safe number to aim for. The AKC says one or two pieces probably will not cause a major problem, but a dog can get very sick even without eating a large amount, so call your vet if your dog eats any.

Can dogs eat pecans in the shell?

No. PetMD warns that pecans in the shell can be a choking hazard if swallowed whole and may cause an obstruction in the digestive system.

My dog eats pecans that fall from our tree. Is that a problem?

Yes. Fallen nuts can be moldy, and PetMD recommends keeping dogs from eating pecans off the ground. Rake up fallen nuts and supervise your dog in the yard during pecan season.

Can dogs eat pecan pie?

No. PetMD says pecan pie is not safe for dogs because of the high-fat nuts plus sugar, corn syrup, and butter.

The Bottom Line

Dogs should not eat pecans. A single dropped piece is unlikely to cause serious harm, but pecans are high in fat, can carry molds that cause tremors and seizures, and can cause choking or blockages. Pecan pie and candied pecans add sugar and butter on top of that. This fall, keep the nut bowl and dessert table out of reach, clear fallen pecans from the yard, and call your vet or a pet poison hotline if your dog gets into them.
