I hope there isn't a topic started on this already, but if there is, would someone be kind enough to point me in the direction of it?

I've noticed that some of you feed your doggies some very expensive food. My question is this. Is the "regular" food bad for them? I have 2 dogs...PJ (cocker spaniel), and Bailey (attention hound), and they both love Pedigree and Purina Dog Chow, with Moist and Meaty mixed in.

Also, is canned food bad for them? I've heard it can make them overweight in a hurry.I only give them canned food once or twice a year because of this.
