Yes, most dogs can eat a little plain peanut butter. The word that matters is plain. The jar that helps a pill go down and the jar that sends you to an emergency clinic can sit on the same shelf and look like cousins.
Peanut butter is popular because it smells like a project. Dogs will work at a stuffed toy for a long time if the payoff is that smell. That is useful. It is also how a toxic sweetener gets eaten in one sitting if you did not read the back.
