@bullie84 not sure if you have read more on our forum yet but no, Iams is not a wise choice for any dog. It is full of bad ingredients, adding 'natural' to the title will never change what has been done to this food and the manufacturer who makes it.
Please view the dog food ratings and other related articles to learn more, and I hope you have found a great food for your bully! Sorry your question went unanswered.
