Like William Wegman, Carli Davidson does interesting and creative dog photography. This image is from her "Shake" series:
She takes the photos with an extremely high shutter speed to record every single nuance of the dog's shaking. I find this scientifically interesting and probably valuable, but as art, I don't particularly like most of it. The ones I do like are those that show the dog looking recognizably like itself.
Carli Davidson also has a Pets with Disabilities project that she started after seeing a disabled German Shepherd playing with his owner on the beach.
An interesting person and an interesting photographer. You can see and purchase her work on her website: http://www.carlidavidsonphotography.com/#/Portfolio/Animals/12/
