Is it okay to feed Maltese peanut butter?

Is it okay to feed maltese peanut butter straight from the jar (e.g. Skippy or Jif). If so, what brands and kinds (creamy or chunky) would be good for a maltese of 6 months? Wouldn't peanut butter be too oily for a maltese's diet?

• Well, I think you should stop feeding your dog peanut butter. For one, it has way to much sugar, and all that sugar wasn't made for dogs to eat. Take from me, my dog loves to eat sweets,(e.g ice cream ,chocolate, cookies) but I don't feed her that know because I know its painful in the future.
