Peanut Butter: Only with care
Generally safe — but ONLY if xylitol-free.
Plain peanut butter without xylitol is safe as an occasional treat. Many brands now use xylitol (an artificial sweetener) which is extremely toxic to dogs. Always check the ingredient label before feeding.
What makes it harmful: Xylitol (only if present)
For medium dogs (20–60 lbs)
1–2 teaspoons is fine as an occasional treat. Always verify no xylitol.
