She has dry food available to her at all times and feed her moist food in the morning and the evening. Plus, I will feed her little bits of chicken, cheese, chicken noodle soup or whatever (within reason, of course) we are having for dinner.
She also gets bits of dog cookies for going out potty and the occassional dog bone type treat (was getting greenies which she loves but that is around the time she got sick so I no longer give her those).
With as much as she does eat, I would think she would be a little chunk
She is a year and a half old and does like to play, but I would not say extremely active.
