I am on miralax (polyethylene glycol) & dolcolax. i usually eat wheat and whole grains but i had some animal crackers that might have been white. i am scared i will get constipated. is it possible or will i be fine?.

Animal crackers : An occasional nosh of animal crackers shouldnt set you back.

You should be fine: Daily recommended dose of fiber is 25-30 gms and you can't get it by just eating foods. Add a fiber supplement to your diet such as metamucil or konsyl and take it on a regular basis. Small amount of animal crackers should not affect your bowel habbits.
