Quick answer: Only with care. Dogs love it and plain peanut butter is safe — but only if it is xylitol-free. Xylitol (also labeled birch sugar) in some peanut butters can kill a dog, so the label check is not optional.

Dogs love it and plain peanut butter is safe — but only if it is xylitol-free. Xylitol (also labeled birch sugar) in some peanut butters can kill a dog, so the label check is not optional.
The main thing to watch: some brands contain toxic xylitol; high fat.

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.
