I wouldn't assume a scientific study would automatically equate to inhumane treatment of animals.  We all are doing our own unofficial studies with each and every dog we raise whether we acknowledge the data or not.

I'm most interested in knowing more about the effect of diets, socialization and early spay/neuter on long term health.  It would be quite interesting to learn our big dollar diets truly affect long term health and longevity.  I've seen some pretty nice dogs who were fed crap for food.  Certainly noone in the dog food industry would publish a study that proved feeding grocery store brands enhanced anything   One of my thoughts about socialization is in regard to biochemical changes that occur in the body because of fear.  If a dog is well socialized and very comfortable in his own skin, one could draw the conclusion that socialization might equal better long term health.  A well controlled study of clones may determine if the fear chemicals truly had a negative effect on health.

I'd like to see cloning be of benefit to the dogs themselves...not just used as a means to continued human greed at the expense of animals.
