Can dogs eat cashews?
The full picture
Cashews are among the safer nuts for dogs — they're not toxic like macadamias, they don't commonly carry the molds walnuts do, and dogs generally tolerate them. That said, they're still high in fat (pancreatitis risk) and almost always sold salted or flavored. A couple of plain unsalted cashews occasionally won't cause problems for most dogs. A packet of salted cashews will. Honey-roasted, chilli-flavored, and dry-roasted cashews all have problematic additions.

Common questions
My dog just ate a small amount of cashews — what should I do?
A small accidental mouthful of cashews is usually not an emergency, but it depends on your dog's size and what else was involved. Watch for vomiting, diarrhea, lethargy, or unusual behavior over the next 12–24 hours. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 if you see any symptoms or if your dog is small or young.

What's a safer alternative to cashews?
See the alternatives section above. In general, plain cooked meat (no seasoning), plain vegetables like carrot or green bean, or dog-specific treats are always a safer choice than human foods with uncertain risk profiles.
Can cashews make a dog sick long-term?
Repeated small exposures to cashews can be worse than a single large accident, depending on the specific risk. Some foods cause cumulative damage (like onion/garlic affecting red blood cells over days), while others just cause repeat GI upset. If your dog has eaten cashews multiple times, mention it to your vet at the next visit.
