I use a grooming table that was made for Saints and Danes, so, it is HEAVY DUTY. It isn't lightweight, but I can move it myself. http://jbarkennels.com/mambo/content/view/16/27/ I have successfully put large collies on it

I am not experienced with color gels, so I won't even go there

I bring a pet hair tape thing(you know, that you use on your clothes) and will run it over a dark cover. And yes, dogs shed all over the dark stuff!!!

I have a rolling trunk I drag around with me. Though I only usually use 2 lights, I tend to bring 4. Just in case I want to do something different.

If you forget a squeaky toy, what works for me really well is to say in the most GOD AWFUL high pitched voice(that may make a human hit you) Are your PREEEETYYY? It is horrible, but if works. The dogs all twist their heads and perk their ears. It is awful sounding though
