Are Cashews or Peanuts Better for Dogs?
When it comes to sharing human snacks with your furry friend, nuts like cashews and peanuts may seem harmless. However, not all nuts are created equal in the eyes of canine health. In this guide, we examine whether cashews or peanuts are a better option for dogs and outline the precautions every pet owner should follow.
Cashews: A Cautious Treat for Dogs
Cashews are non-toxic but high in fat, making them suitable only in small quantities. They can be safely enjoyed by most dogs as an occasional treat, provided they are:
- Shelled – The shell contains urushiol, an irritant also found in poison ivy.
- Roasted or baked – Raw cashews may contain toxins harmful to dogs unless properly processed.
- Unsalted and unseasoned – Salt and spices can be toxic.
- Given in moderation – High fat content can lead to obesity or pancreatitis.
Cashew butter and cashew milk are also safe if homemade or free from additives like xylitol, artificial sweeteners, and added oils.
Peanuts: A More Familiar Option
Peanuts, often found in peanut butter, are more commonly fed to dogs. While technically legumes and not true nuts, they are generally safe if they meet similar criteria:
- Unsalted and unflavored
- Free of xylitol – An artificial sweetener extremely toxic to dogs
- In moderation due to fat content
Peanut butter is often used for training or to hide medication, but store-bought versions must be carefully reviewed for harmful additives.
Risks of Cashews and Peanuts
Both cashews and peanuts pose several shared health risks for dogs:
- High fat content – Can contribute to weight gain and pancreatitis
- Digestive issues – Vomiting and diarrhea may occur from overconsumption
- Allergic reactions – Manifesting as itching, hives, or swelling
- Choking hazard – Especially for small dogs or puppies
- Mold contamination – Moldy nuts can be dangerous
For that reason, both nuts should be given only on occasion and as part of the 10% treat guideline—no more than 10% of your dog's daily caloric intake should come from treats.
Which is Better: Cashews or Peanuts?
Between the two, cashews are slightly safer when pure, roasted, and unsalted, but offer little to no advantage over peanuts nutritionally. Dogs may tolerate peanuts better due to familiarity and the prevalence of peanut butter-based treats in canine diets. However, each dog is different, and reaction to either nut can vary based on size, breed, and health history.
Which Dogs Should Avoid Nuts Altogether?
Certain conditions make nut consumption risky or dangerous:
- Dogs with pancreatitis or obesity
- Dogs prone to bladder stones or hyperlipidemia
- Puppies and very small breeds who face higher choking risks
- Dogs on prescription diets
Always consult a veterinarian before introducing new treats to dogs with known health issues.
Healthy Alternatives to Nuts for Dogs
If you're looking for safer, lower-fat snacks, consider:
- Carrot sticks
- Apple slices (without seeds)
- Blueberries
- Green beans
These alternatives are lower in calories and offer vitamins and fiber without the fat content of nuts.
Final Thoughts: Choose With Care
Cashews can be a tasty treat for dogs when carefully prepared and served in moderation, while peanuts—particularly peanut butter—are familiar and widely accepted. Remember, neither should be a staple of your dog’s diet. The highest priority should always be your dog’s safety, weight, and overall health.
If unsure, start with a small amount and observe your dog’s reaction. Stop immediately if digestive or allergic symptoms occur and consult your veterinarian regularly when introducing new treats.
