Quick answer: Only with care. Plain cashews are not toxic, but they are fatty and calorie-dense, so they are strictly a one-or-two treat.
Why Cashews Needs Care
Plain cashews are not toxic, but they are fatty and calorie-dense, so they are strictly a one-or-two treat.
The main thing to watch: high fat; mixed nuts may contain toxic macadamias.
How to Serve Cashews Safely
Unsalted, unflavored, and just one or two at a time. Never feed mixed nuts, which may include macadamias.
What If Your Dog Already Ate Cashews?
For most dogs, a small accidental taste is not an emergency. Watch for vomiting, diarrhea, or loss of appetite over the next 24 hours, keep fresh water available, and call your vet if symptoms appear — or sooner if your dog is very small, very young, or has existing health conditions.
