What a Security Dog Handler Adds On Site
A trained dog and handler bring a visible, mobile presence to your site. Patrols can adapt as the layout, activity or risk level changes and work alongside CCTV, alarms and existing guarding where passive monitoring alone is not enough.
Changing Site Layouts
Patrols can be adapted as access points, storage areas, boundaries and work phases change.
Repeated Theft or Trespass
A stronger on-site presence can be introduced when incidents continue despite existing controls.
Unauthorised Access or Occupation
A visible team can support site management where traveller activity, trespass or unauthorised occupation is a concern.
Valuable Assets Remain on Site
Useful where plant, tools, fuel, cabling, materials or vehicles remain exposed outside working hours.
Active and Unoccupied Periods
Cover can be planned around live operations, reduced activity and the hours when fewer people are present.

Security dog handler cover across the UK, subject to team availability and your site requirements.
Questions About Site Security Cover?
Quick answers about pricing, deployment, qualifications, night cover, site coverage and working safely around people.
How much does a security dog handler service cost?
Pricing depends on your site size, risk level, required hours and the number of teams needed. We review the requirement first, then provide a clear quotation for the cover your site needs.
How quickly can you deploy security dog handlers?
Deployment depends on your location, site requirements and team availability. For urgent requests, we will confirm what cover can be arranged and when before the team starts.
What qualifications do your security dog handlers hold?
Handlers hold the appropriate SIA licence and undergo BS 7858 vetting. Recognised dog handler training includes NASDU where applicable. We confirm the assigned team’s credentials during procurement, with deployments planned around BS 8517-1 aligned practices and dog welfare.
Are security dog handlers more effective than static security guards?
It depends on the site. A dog-handler team adds visible deterrence, active patrol coverage and earlier detection, but it is not an automatic replacement for a fixed number of guards. We recommend the right combination after reviewing your layout, duties and risk level.
Can you provide out-of-hours and night security?
Yes. Night, weekend, temporary and ongoing cover is available subject to location and team availability. These are often the periods when exposed sites face the greatest risk of theft, trespass, vandalism and unauthorised access.
What is the advantage of using a security dog handler over CCTV alone?
CCTV can monitor and record activity, but it cannot physically patrol blind areas or provide an on-site human response. A dog-handler team adds visible deterrence, active checks, earlier detection and controlled escalation. Some sites benefit from using both.
Are security dogs safe around workers and visitors?
The dog stays with its trained handler. Patrols are planned around workers, visitors, entrances and public areas. Any concern is reported using the agreed process.
