If you've done dog training, you'll appreciate the difficulty. Today I had one in a sit, one in a down and told them both to stay. Then I threw treats around the room and told them to "leave it". They really wanted the treats but were good puppies and didn't break too often. Tossing the treats made them more animated, but it was risky since I was doing the shoot by myself and so I didn't have anyone else helping me keep the dogs in line. Patience and a positive attitude and many retakes allowed me to get the shot that I had in my head!
