Can dogs eat cashews?
Short answer: Yes, plain unsalted cashews are safe for most dogs in small amounts. But: never salted, flavoured, or seasoned; never in large quantities; never instead of a meal. Full guide below.
Safe?
YES
Plain, unsalted, in small amounts
Avoid
SALTED
Plus flavoured, honey-glazed, spice-coated
Max per day
1–2 (small), 3–4 (medium), 4–6 (large) plain cashews
The short version
Cashews are not on the canine toxic-foods list. Unlike grapes, raisins, chocolate, macadamia nuts, or anything with xylitol, plain cashews don't contain compounds that are inherently poisonous to dogs. So a stray kernel that your dog grabs from the floor is unlikely to cause a problem.
But "not toxic" isn't the same as "good for dogs." Cashews are high in fat (~44g per 100g) — a single cashew is roughly 9 calories. Dogs don't need cashews nutritionally; they're treat-tier food, not meal-tier.
Safe quantity by dog size
- Small dog (under 10 kg / 20 lbs): 1–2 plain cashews
- Medium dog (10–25 kg / 20–55 lbs): 3–4 plain cashews
- Large dog (over 25 kg / 55 lbs): 4–6 plain cashews
This is a daily maximum, not a recommendation. Most dogs do fine with much less or none. Treats should be under 10% of total daily calories.
What to absolutely avoid
- Salted cashews — sodium toxicity risk. Most retail cashews are salted; check the label or buy raw.
- Honey-glazed, spice-coated, roasted-and-salted — flavourings often include garlic powder, onion powder, or other ingredients that can be toxic to dogs.
- Cashew butter with additives — many cashew butters contain xylitol as a sweetener; xylitol is extremely toxic to dogs.
- Raw/unprocessed cashews — true raw cashews (which never reach retail anyway) contain CNSL (cashew nut shell liquid) residues that are caustic.
- Cashew shells, husks, or any non-kernel cashew material
Risks even with plain cashews
- Pancreatitis — high-fat foods can trigger pancreatitis in susceptible dogs. Breeds at higher risk: Miniature Schnauzers, Cocker Spaniels, Yorkshire Terriers.
- Choking — for small breeds or dogs that don't chew, whole cashews can lodge in airway. Crush before giving to small dogs.
- GI upset — diarrhea, vomiting, gas. Most common with larger quantities.
- Weight gain — calorie-dense food, easy to overdo
- Allergic reaction — rare but possible. Watch for skin irritation, itching, swelling, vomiting after first introduction.
FAQ
Can dogs eat cashews? +
Yes — plain, unsalted, unflavoured cashews are safe for most dogs in small quantities. They are not toxic to dogs the way grapes, raisins, chocolate, or macadamia nuts are. Limit to a few kernels at a time and only as an occasional treat.
How many cashews can a dog eat? +
For a small dog (under 10 kg / 20 lbs), 1-2 plain cashews. For a medium dog (10-25 kg / 20-55 lbs), 3-4 cashews. For a large dog (over 25 kg / 55 lbs), 4-6 cashews. Always plain, unsalted, unflavoured. Never as a meal — cashews should be less than 10% of daily calorie intake from treats.
Are salted cashews bad for dogs? +
Yes. The added sodium in salted, seasoned, roasted-and-salted, or honey-glazed cashews exceeds safe canine intake. Even small amounts can contribute to sodium toxicity over time. Always plain unsalted cashews only.
Can puppies eat cashews? +
Veterinary guidance generally advises against giving cashews (or any high-fat nut) to puppies under 1 year old. Puppy digestion is more sensitive; even small amounts can cause GI upset.
What about cashew milk or cashew butter for dogs? +
Plain unsweetened cashew milk in tiny amounts is generally safe but offers no nutritional benefit. Cashew butter often contains added salt, sugar, or oils — check the label. If giving cashew butter, ensure it's 100% cashew with no additives, and limit to a teaspoon-sized amount for medium dogs.
What are the risks? +
Three main risks: (1) high fat content — can trigger pancreatitis in sensitive dogs, (2) choking hazard for small breeds, (3) any added salt, garlic powder, onion powder, or xylitol (sweetener) in flavoured cashews is dangerous to highly toxic for dogs.
What nuts should dogs never eat? +
Macadamia nuts (toxic to dogs — can cause weakness, tremors, hyperthermia), walnuts (especially mouldy — produce tremorgenic mycotoxins), pecans, almonds in bulk (choking + GI risk), pistachios (high fat, often salted), and any nut with xylitol-containing peanut butter. Plain cashews, peanuts, and unsalted almonds in moderation are generally safer.
If your dog ate a lot of cashews
If your dog accidentally ate a large quantity (say, half a bag of salted cashews) and you notice:
- Vomiting, diarrhea, or excessive thirst
- Lethargy, tremors, weakness
- Abdominal pain or distended belly
Call your vet or the ASPCA Animal Poison Control Center (888-426-4435). Pancreatitis from high-fat ingestion is the main concern. If symptoms are severe, treat as an emergency.
