Is Your Dog Nuts About Nuts? The Good from the Bad.

Many dogs absolutely love almonds, especially with the wide variety of flavored and seasoned almonds popular today. While almonds are not considered toxic, they are very high in fat and not easily digested which can lead to upset stomach and gastrointestinal discomfort.

Verdict: An occasional almond is ok to feed, but there are much safer, healthier treats available.

Black Walnuts

Black walnuts contain a toxin known to cause vascular disease in horses but has not been shown to cause the same in dogs. However, eating black walnuts can cause gastrointestinal upset or a dangerous obstruction. When moldy, black walnuts can contain tremorgenic mycotoxins which can cause seizures or neurological symptoms.

Verdict: Do not feed.

Brazil Nuts

Like almonds, Brazil nuts are not toxic to dogs, but are high in fat and not easily digested. A dog that eats Brazil nuts may experience an upset stomach.

Verdict: Ok on occasion, but there are much safer, healthier options available.

Cashews

Cashews are not toxic to dogs and are generally safe to feed in moderation – as long as they are cooked or roasted. Raw cashews do contain a toxin that is eliminated through cooking. Because of their fat content, cashews can cause an upset stomach.

Verdict: Do not feed raw cashews, but cooked or roasted cashews are generally safe in moderation.

Chestnuts

American Chestnuts are not toxic to dogs, however, they can pose a choking or obstruction risk and can lead to gastrointestinal distress when eaten.

Verdict: Ok if ingested, but avoid in favor of better options.

English Walnuts

The most commonly snacked type of walnut, English walnuts can lead to upset stomach and gastrointestinal distress or obstruction. Like Black or Japanese walnuts, moldy English walnuts can contain tremorgenic mycotoxins (toxic chemical products produced by fungi) which can cause seizures or neurological symptoms.

Verdict: Do not feed.

Hazelnuts

Hazelnuts are not toxic to dogs and are generally safe to feed in moderation. However, because of their size and shape, they can pose a choking or obstruction risk to smaller dogs.

Verdict: Ok to feed on occasion to larger dogs.

Hickory Nuts

Another nut known to cause laminitis in horses, but not yet proven to cause the same vascular disease in dogs. Hickory nuts can cause gastrointestinal upset or an obstruction. And, like walnuts, moldy hickory nuts can contain tremorgenic mycotoxins which can cause seizures or neurological symptoms.

Verdict: Do not feed.

Japanese Walnuts

Although Japanese Walnuts are not toxic, they can cause gastrointestinal upset or intestinal obstruction. Like other types of walnuts named, moldy Japanese walnuts can contain tremorgenic mycotoxins which can cause seizures or neurological symptoms.

Verdict: Do not feed.

Macadamia Nuts

Macadamia nuts are commonly listed as one of the top “human foods” to avoid feeding your dog. These nuts contain an unknown toxin that can lead to neurological issues and are very, very high in fat, which can put your dog at risk for serious gastrointestinal distress or lead to pancreatitis.

Verdict: Absolutely do NOT feed.

Peanuts

Peanuts are not toxic to dogs and are frequently used in healthy and safe treats as dogs tend to love the taste. Any peanuts served to your dog should be raw or roasted, unsalted, and without their shells. Peanut butter used as a treat should be natural and only include peanuts without the addition of sugars, salts, or artificial sweeteners.

Verdict: A great treat in moderation.

Pecans

Like walnuts and hickory nuts, pecans have been known to cause laminitis in horses. Feeding your dog pecans can result in gastrointestinal distress or an obstruction. Additionally, moldy pecans can contain tremorgenic mycotoxins which can cause seizures or neurological symptoms.

Verdict: Do not feed.

Pistachio Nuts

Pistachios, although not toxic to dogs, are another variety of nut which is rich in fat and can lead to upset stomach or pancreatitis.

Verdict: An occasional pistachio, without the shell, is ok, but there are much safer, healthier treats available.
