The problem at the South African Police Service Dog Breeding Centre was that most of their progenies were unsuitable as police dogs. Behaviour tests were developed specifically for police dogs to predict their efficiency as adults. Puppies from the age of 8 weeks were exposed to situations that they probably would encounter in their work as police dogs. These experiences included crossing of obstacles, retrieval of objects, startle stimuli and aggression. In the longitudinal study of 2 years it was found that all the tests had statistical significance to a greater or lesser extent, except the gunshot test. The most significant tests were retrieval at 8 weeks and aggression at 9 months. These tests thus enable selection for suitable dogs as early as 8 weeks of age, but not later than 9 months. The conclusion is that reliable tests can predict adult police dog efficiency and in doing so, save unnecessary training and other costs on unsuccessful dogs. (C) 1999 Elsevier Science B.V.

The separation of young dogs from their mother at the age of 6 weeks had a negative effect on the physical condition and weight gain of separated pups compared to that of pups with maternal contact till 12 weeks. Disease susceptibility and mortality was higher in pups with a shorter maternal contact period. These factors were related to behavioural measurements of separation stress. However, early separation had no significant advantage to socialisation with humans, provided that separated and nonseparated pups had daily human contact. Early separation therefore did not improve dog/human bonding processes but lowered condition and increased mortality in separated pups
