Food safety
Can dogs eat peanut butter?
Yes, but be careful
Fine as an occasional treat — but only if it doesn't contain xylitol or birch sugar. Read the label every single time, even on a brand you know.
How much
A teaspoon smeared in a lick mat
If your dog has already eaten it
Xylitol-free only.
Being honest about this
Dogs differ, and amount matters — a crumb of something rich is not the same as half a packet. Treats of any kind should stay under a tenth of what your dog eats in a day. If you're unsure, your vet would far rather take the call.
