My 3yr old puggle won't touch her food until very late in the afternoon. She used to gobble it up right when I put it out.(9:00am). She would finish it in about 2min. And then I would pick her bowl up. I got her wormed 2months ago. She won't eat any commercial dog cookies. Either. Why?

I see nothing wrong or even worrisome about any of this. Neither my current nor last dog were big fans of dog biscuits or cookies or little treats that are baked. Eating late in the day is very common. All my dogs have. (Mine get to have a bit of dry kibble available most times so they don't wolf food down at the real meal, as wild animals do, never knowing when the next meal is coming.)
