Peanut butter is one of those treats that dogs seem to lose their minds over, and it has become a staple in the dog owner’s toolkit for everything from Kong stuffing to hiding tablets. So, can dogs eat peanut butter? Yes, most dogs can, but there is one crucial thing to check before you hand any over, and it is not something worth skipping.
Plain, unsalted peanut butter with no added sugar is safe for dogs in moderate amounts. It contains protein, healthy fats, niacin, vitamin B6, and vitamin E, which makes it a more nutritious treat option than many commercial alternatives. It is also one of the more effective ways to encourage a fussy dog to take their medication, since the strong smell and sticky texture make it very hard to avoid.
The Xylitol Warning
This is the most important thing to know when it comes to peanut butter and dogs. Some peanut butter brands, particularly those marketed as low-sugar or diet options, use xylitol as a sweetener. Xylitol is extremely toxic to dogs. Even a small amount can cause a rapid drop in blood sugar, liver failure, and in severe cases, death. It acts very quickly, so there is no time to take a wait-and-see approach if your dog has eaten peanut butter containing xylitol.
Always read the label before giving peanut butter to your dog, every single time you buy a new jar. Look for xylitol in the ingredients list and put it back if you find it. This applies to any nut butter, not just peanut butter. Dogs with existing diabetes need particular monitoring around anything that can affect blood sugar, so it is worth being extra careful and choosing a brand you have verified as safe.
How Much Peanut Butter Can a Dog Have?
Peanut butter is high in fat and calories, so moderation is important. For a large dog, a tablespoon or so a few times a week is a reasonable amount. Smaller dogs should have considerably less, perhaps just a teaspoon. Too much over time can contribute to weight gain and, in some dogs, can trigger pancreatitis, which is a painful and potentially serious condition. Dogs with heart conditions or those already on a low-fat diet should avoid peanut butter or have it very sparingly.
Which Peanut Butter Is Best for Dogs?
Look for natural peanut butter that contains only peanuts, or peanuts and a small amount of salt at most. Avoid varieties with added sugar, palm oil, or any artificial sweeteners. Some brands are now marketed specifically as dog-safe peanut butter, which takes the guesswork out of label-reading. If you are baking homemade dog treats that include peanut butter, the same rules apply to the jar you bake with.
Dogs with skin problems or allergies can occasionally react to peanuts, so if your dog has known food sensitivities it is worth introducing peanut butter cautiously and watching for any reaction.
Good Ways to Use Peanut Butter
Stuffed into a Kong and frozen, peanut butter keeps a dog occupied for a good while and makes for a brilliant boredom-buster. Spread thinly on a lick mat, it can help to calm anxious dogs during grooming or nail trims. Mixed with banana and frozen in moulds, it makes an excellent summer treat that most dogs will go absolutely mad for.
