The fancy has traditionally selected dogs for breeding programs based on arbitrary conformation traits, rather than soundness of structure and overall health.

A year ago Time™ Magazine published a pre-Christmas exposé cover story on hereditary problems in purebred dogs.

The threat of punitive legislation, already a reality in Europe, is widespread in the USA and the contagion seems certain to reach Canada as well.
