Starla does the EXACT same thing. We finally figured out that she is the leaving the triangle shaped bits in the bowl and on the floor but eating everything else. I'm not sure what flavor those triangle kibbles are, but they must be pretty nasty for a pig like her to not eat them.Roscoe is the only one who chews kibble, by kibble! Takes him forever to eat 1cup of food! We joke and say that is why he is the skinniest beagle of the three!
