Jim, I would not tell someone to take their dog to training. Part of being a pet photographer is being able to deal with those spoiled spastic animals. The owner is not unhappy with the behavior of the pet. It is like telling a mother their kid is a brat and a good spanking might cure their problems

I had two, sweet, but spastic standard poodles in my studio and I think they were one of the toughest clients I have had. I did manage to get some really nice shots of them. It took awhile and I had to have a lot of patience to let them wind down first.
