Are you wondering if dogs can eat pecans? While these tree nuts are a nutritious, protein-rich snack for humans, they aren't the most Fido-friendly treat. Dogs should not eat pecans since they contain a toxin that can lead to tremors, seizures, and even damage a dog’s neurological system. Learn more about why your dog should not eat pecans and other issues it can cause.

Are Pecans Safe for Dogs?

Here are some mild risks that pecans can cause:

Toxic Risk

If your dog happens to snatch a pecan that has accidentally fallen to the floor, it's likely nothing to worry about, but pecans are definitely not safe to offer your dog as a treat. These particular nuts may contain a toxin known as juglone, which can be harmful to your pet (juglone is also severely toxic to horses).

Mold Risk

Like walnuts, pecans are also susceptible to mold, which contains tremorgenic mycotoxins, which are harmful substances produced by some types of molds. If consumed by a dog, these toxins can lead to tremors, seizures, and even damage a dog’s neurological system. Pecans are a type of tree nut that can also contain another natural poison, aflatoxin, which is produced from a mold that grows on pecans known as Aspergillus.

If your dog ingests a pecan that has become moldy (which can happen easily and quickly on the shells), they can experience symptoms that include seizures and other neurological issues. While pecans are harmless to humans who don't have a nut allergy, the GI systems of dogs aren't strong enough to withstand the toxins that may be lurking on the outside of these nuts.

Choking Hazard

Pecans can be a choking hazard for dogs if eaten whole. Like many nuts, pecans can also be difficult for dogs to digest, and their size and texture can cause serious (and even life-threatening) intestinal blockages, particularly in smaller breeds. These blockages often require surgery.

HIgh Fat Content

Nuts like pecans are high in fat, and thus can upset your pooch's stomach and lead to common GI symptoms like diarrhea. Consuming pecans and other nuts can also lead to the development of serious conditions like pancreatitis, an inflammation of the pancreas, or gastroenteritis, which occurs when the dog's stomach or intestines becomes inflamed.

What To Do If Your Dog Eats Pecans

If your dog eats one pecan that fell on the floor, this isn’t a huge cause for concern. Just be sure to monitor them for signs of illness. However, if your dog accidentally ingests either a moldy pecan or has managed to steal a large amount of these nuts (think a handful or more), call a vet right away as quick treatment can prevent serious complications. Immediate symptoms to look out for include:

• Vomiting
• Diarrhea
• Increased urination

Sometimes these symptoms will only last a few hours—but in more serious cases, the vomiting and diarrhea will become intense, and you’ll need to take your dog to the vet immediately, as their condition can become fatal if left untreated.

Are Other Nuts Safe for Dogs?

Veterinarians generally don't recommend any nuts for dogs. Some may be considered less harmful, such as peanuts, cashews, and almonds. However, although these nuts all contain nutrients like fiber and protein, they can be choking hazards, carry the risk of causing stomach distress or intestinal blockages, and they are often packaged with potentially harmful additives like salt and other flavorings.

You should never offer your dog macadamia nuts or hickory nuts, as they are both considered toxic for dogs. Black walnuts and pistachio nuts are also known to be particularly harmful for our pets. If your pet ingests more than a few accidentally, seek immediate veterinary advice.
