Why

Plain, unsalted, shelled peanuts are not toxic to dogs, and a few make an acceptable treat. They are high in fat, so quantity risks stomach upset and pancreatitis; salted peanuts add the sodium problem; and shells are a choking and obstruction hazard.

Signs to watch for if your dog has eaten peanuts

Vomiting
Diarrhea or loose stools
Loss of appetite
Belly discomfort or unusual tiredness

Signs vary with the amount and with the individual pet, and some appear only after a day or more. Their absence does not mean your dog is in the clear — call rather than watch.

What to do now

Serve it plain, in small pieces, as an occasional treat. Keep all treats to under about a tenth of daily calories, and introduce anything new in a small amount so you can spot a sensitive stomach.

Never induce vomiting and never give any medicine unless a vet tells you to. With some substances it causes more damage than the poison. This page tells you when to get help — it never tells you how to treat at home.
