There's no question that dogs love the peanute butter, but you may have wondered if it's actually good (or bad) for them. Although it's an ingredient in a lot of commercial dog treats, the answer may surprise you. Here's the lowdown on peanut butter for dogs, as well as some safe alternative human foods dogs can eat.
Xylitol & Other Cautions About Peanut Butter

Many brands of peanut butter contain added ingredients that are unhealthy and even harmful for dogs. Some peanut butters include an artificial sweetener called xylitol, which is extremely toxic to pets.
Often, peanut butter contains added sugar that can contribute to weight gain. Peanut butter also typically contains added salt that makes it high in sodium, and certain fats, such as palm oil. Pet parents should check with their veterinarian to ensure that peanut butter is acceptable for their pet, especially those pets with health conditions.
Can Dogs Eat Peanut Butter?
While there are reasons to be cautious about feeding this sticky treat to your dog, the news isn't all bad. Natural peanut butter is a great source of protein, B and E vitamins, and healthy monounsaturated fats, says the AKC. There are a lot of commercial treats with peanut butter that can be fun for your pet. But as with all treats, they should be limited to 10% of daily calories so not to upset nutritional balance. If your dog is crazy about peanut butter, they can eat it in moderation as long as you're careful to check the ingredients and run it by your veterinarian first. Look for all-natural, unsalted peanut butter that lists peanuts as the only ingredient.
You could also make peanut butter at home by simply grinding peanuts in a food processor. If you choose to go this route, be sure to source your peanuts from a reputable source. Peanuts found in nature can sometimes have a fungus on them called Aspergillus flavus and Aspergillus parasiticus, the fungus that produces the aflatoxins (cancer producing toxins) says The National Cancer Institute. This is why in the U.S. the FDA inspects foods like peanuts and peanut butter for human consumption to reduce the risk for people.
Remember that too much of a good thing isn't good for your pup. Between the high fat and calorie content and the threat of aflatoxins, it's best to limit even natural or homemade peanut butter to an occasional treat.
