There is no simple answer to this question: dogs can eat some kinds of peanuts and not others. Peanut butter might be safe for your dog. There are big health benefits to both of these things. But there are also risks and you certainly shouldn’t overdo it!
So, let’s dig in a little deeper.
Basically, peanuts on their own are relatively safe for dogs. They are also a good source of protein, fiber, healthy fats, vitamin B6, and other things.
One issue is that dogs don’t need as much of many of those things. They don’t need as much fiber, for instance, and while peanuts provide a perfectly safe amount of fiber for humans, it may be a little bit too much for dogs and cause digestion problems, constipation, diarrhea, and more issues.
The same goes for fats –too much fat can be a risk.
The other issue is that most of the peanuts that humans enjoy are not plain raw peanuts but rather peanuts that have a lot of added sugar, salt, and/or fat. Peanut butter likewise can be incredibly fatty or have a whole lot of sugar added!
The basic answer is that the closer the peanut is to being a natural peanut and the less processed it is, the more likely it is to be safe for your dog. With that said, even the most natural and un-tampered-with peanut in the world should still be enjoyed only in moderation by your dog, seeing as they can be unhealthy in larger quantities.
This post will explain a little more about how to help your dog enjoy peanut and peanut butter in a way that’s safe.
