Pecan
CautionThe AKC says pecans should not be given to dogs. They contain juglone, the same compound found in walnuts, and Aspergillus mold on pecan shells produces aflatoxin and tremorgenic mycotoxins that cause tremors and seizures.

More about this food
Pecans are harmless to people and a bad idea for dogs. The American Kennel Club states that pecans should not be given to dogs, and advises contacting a veterinarian if a dog eats them even in a small amount. Four separate problems stack up.
Juglone comes first. Pecans contain juglone, the same compound found in walnuts, and it is harmful to dogs. It irritates the digestive tract and produces severe vomiting and diarrhea.
Mold is the real danger. Aspergillus grows readily on pecan shells and produces aflatoxin, and molds on nuts also generate tremorgenic mycotoxins. A dog that ingests them can develop tremors, seizures and other neurological signs. This is the reason yard pecans matter so much: nuts that fell weeks ago, sat through rain, and got raked into a pile are exactly the ones carrying mold, and a pecan that looks fine offers no guarantee. If you have a pecan tree, the ground under it is the hazard, not the pantry.
Fat is third. Pecans are very high in fat, which can trigger pancreatitis -- vomiting, diarrhea, loss of appetite and lethargy, typically 24 to 72 hours after the meal. The ASPCA groups almonds, pecans and walnuts together as nuts containing high amounts of oils and fats that can cause digestive upset and potentially pancreatitis.
Size is fourth. A pecan half is a convenient size to swallow whole, so choking and obstruction are on the table, shell fragments included.
On timing: GI signs come on within hours, while mycotoxin signs typically start 30 minutes to 3 hours after ingestion -- trembling, exaggerated startle to sound or touch, a wobbly gait, flicking eyes, and seizures. Waiting through that raises body temperature and damages muscle, and the picture deteriorates fast.
So: if your dog ate pecans, call, even for a small amount. The AKC notes a dog can get very sick without eating a large quantity, and recommends an emergency clinic if your regular veterinarian is unavailable. You can also reach the ASPCA Animal Poison Control Center at (888) 426-4435. If tremors or seizures have already started, call from the car. Do not induce vomiting at home -- feeding anything to a seizing dog risks aspiration pneumonia, and emesis is contraindicated in that state. Pecan pie is a bigger conversation than the nut: butter, sugar and corn syrup make a pancreatitis-grade fat and sugar load, and some recipes add chocolate or bourbon, so tell the clinic which pie and roughly how much.
Frequently asked questions
- My dog ate one pecan. Do I really need to call?
- Yes, at least by phone. The AKC advises contacting a veterinarian even after a small amount. One fresh pecan is unlikely to harm a large dog, but you cannot tell by looking whether a nut carries mold, so let a clinician make that call.
- He got into pecans that fell from the tree in the yard.
- Treat that as the higher-risk version and call now. Nuts on wet ground grow Aspergillus and other molds that produce aflatoxin and tremorgenic mycotoxins, and neurological signs can start within 30 minutes to 3 hours.
- She ate a slice of pecan pie. Same thing?
- Worse in a different way. Butter, sugar and corn syrup make it a serious pancreatitis risk, and some pies contain chocolate or bourbon. Call your vet or the APCC at (888) 426-4435 and tell them the recipe and portion.
