I'm trying to improve the results of my candid dog photography.

Some current efforts are posted at http://www.photo.net/photodb/folder?folder_id=600414

It's clear that these are "grab-shots" taken on various public outings when it's seemed to me not possible to pose the animal, arrange backgrounds, compensate for poor lighting (except to use fill-flash), etc.

For the most part, I've hopefully relied on having the right camera settings and getting a reasonable composition.

Any suggestions on how I could improve these kinds of pics would be much appreciated.
