If you compare a security dog to the call out service of a security guard you will find that it more cost efficient, as a guard may visit your site 2/3 times a night. A dog is kept on site, whole time you site is unoccupied.
We understand that you probably have security arrangements for your establishment, however things can happen and do happen.
Guard dogs play a big part in security not only do they protect the dog handlers, a good guard dog will pick up human scent from 500 metres away from where the dogs are.
The security dog is primarily an early warning system, it is their job to detect the approach of any intruder while he or she are a considerable distance from there intended target.
