If she is not eating her poop any longer then you have found the proper amount of pineapple to feed her. I usually don't suggest putting it into the food directly but feeding chunks as a snack several times a day. The idea is to break them of the habit of poop eating and once they stop you should eventually begin to cut back and stop the pineapple. My three are not poop eaters and love to have pineapple too. Maybe you could try easing off adding it to their food and just feed as a snack. If she start to have an interest again you can increase the amount back up to where you were when she was not eating poop.
I've never heard anyone having an issue with the sugar content in a few pieces of pineapple. Plus~it really does work if you are consistent! Congratulations on you NON poop eating pup
