Hello. There is nothing toxic in pecans that would harm a dog. At most, she may have an upset stomach for a day or so & may vomit or have diarrhea. If she feels like eating, you might want to feed her lightly with small meals ( about 1-2 tablespoons at a time ) of cooked ground turkey mixed with plain boiled white rice or low fat cottage cheese. If she seems fine tomorrow, you can resume her regular diet. Thanks for using Petco Pet Education Center, formerly Petcoach.

Pecans are not toxic to dogs, so eating one or two should normally not cause any problems. You might see some mild GI upset if Daisy isn't used to "human food", but we would not expect to see any serious issues :)

Eating a large amount of pecans can be toxic to Tracker. Pecans contain levels of a poison called Aflatoxin, which dogs are very sensitive to and can easily fall ill from it. Dogs will show lethargy, vomiting, and anorexia. In addition, pecans are very high in fat, which can cause pancreatitis in dogs. They can also develop liver failure from eating too many pecans. Tracker needs to see a vet right away if he's been vomiting and is now refusing to eat or drink. Essential oils will not treat this (and many are toxic to dogs if ingested), he needs medical attention from a vet right away. Please take him into a vet now.

Hello. There is nothing dangerous or toxic about pecans by themselves, but the nuts do contain a lot of fats & oils. This could lead to vomiting & diarrhea, & possibly pancreatitis. I would definitely avoid any fatty foods for the next few days & this includes cheese & processed meats. If Charlie feels like eating, only offer him cooked chicken ( no skin or fat ) & cooked whole grain white rice ( not Minute Rice ). He can receive small meals of 75% rice & 25% chicken ( can use jarred chicken baby food, too ) until you are sure there is no vomiting or diarrhea. If he continues to act unwell over the next 36-48 hours, then please see your vet to rule out an inflammatory episode of pancreatitis. Hope all is well & thanks for using Petco Pet Education Center, formerly Petcoach.

The small amount of pecans ingested likely did not put him at risk of serious toxicity. A dog his size would need to eat a large quantity in order to reach toxic levels. As long as he is behaving normally otherwise, you can try withholding food for 24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amounts. Begin with 1 tablespoon of food every hour and gradually increase the amount if there is no vomiting. Feed bland until there has been no vomiting for 48 hours, then transition slowly to the regular diet. Symptoms that should be addressed by your veterinarian include lethargy, persistent vomiting or diarrhea, loss of appetite or abdominal pain.
