I'm bumping this thread up because I am having this problem with Bailey and found lots of handy info here.
I have been trying pineapple for several days now, but so far it doesn't seem to be helping. I'm using little pineapple pieces from fruit cups packed in pineapple juice though. Could it be because of the sugar in these that it's not working? Do I need just plain pineapple?
Also I am feeding Eukanuba and I think that could be part of the problem. That might also be the reason Bailey is often stractching (?

). I want to switch her to a premium food. I'm waiting for Wellness samples. But I don't want to waste the rest of the Eukanuba bag.
