Hi, I've noticed in the last week or so (especially now Summer has just been spayed) that she is getting a pin head and barrel shaped middle (a bit like me). Is this natural? She is eating a lot better than before as she was always picky with food but I give her two cup fulls of skinners at tea time plus the odd treat during the day but nothing to the excess? Is she just maturing or getting fat? She was under 25k when we had her spayed.
