I found your thread when I was browsing around the net, and thought I may be of some help to you.
We actually show dogs, and I can give you alot of insite and options for you for photography at dog shows.
You can do ringside candid shots unless the premium list specifically states that is it limited. Video as well. A premium for example that says that this can not be done, in respect to video, is the Westminster Kennel Club shows in Madison Square Gardens (in a week actually). All rights to video that show belong toUSA network.
Alot of photographers go to shows and take candid shots then put them out on websites for the people to view and purchase. You can advertise in the show catalog for pretty cheap that you were there and the exhibitors will be able to veiw their photos at
WWW.whatever
You can also rent "booth" space for portrait type photos. Alot of photographers do this, they have one person in the booth and one out taking candids...covering all the angles.
Alot of Agility trials will have an official photographer, but the Dog world offers a huge varity of options, you have fiele trials, Agility Trials, Obedience Trials, Conformation shows, Freestyle shows, Flyball Trials, herding trials, Earthdog events, Lure Coursing and who knows what else.
There are AKC show, UKC Shows, Intl Kennel Club shows, ASCA shows and several others.
Feel free to email (aussieu@comcast.net) me with any questions you all may have to get information on shows in your area and what not. (Please put dog show photo information in the subject line)
