Jim; You say person kneeling behind, so I assume you would not make a stage that is 9 ft wide and 8 ft long, basically from the background forward. Sounds like you would prefer a 9 ft wide and maybe 4 ft deep so person can be behind, if needed.

My thoughts, I wanted a platform for the animal to be on that would allow the background to be continuous; I guess I could allow the background to go to conc. fl, over to platform, up platform and over top of platform and down front. Thoughts?
