Guard dogs [[Bark (utterance)|bark]] loudly to alert their owners of an intruder's presence and to scare away the intruder.<ref>{{cite book|url=https://books.google.com/books?id=TvOWH7U3y80C&q=guard+dog+definition&pg=PA47|title=The Dog Law Handbook|first=Paul|last=Clayden|date=1 May 2011|publisher=Sweet & Maxwell|isbn=9780414048188}}</ref>

[[Livestock guardian dog]]s are often large enough—{{convert|100-200|lbs|kg}}—and strong enough to attack and drive away livestock [[predator]]s.<ref name=":0" /> Guard dogs bark to alert their master and to warn of approaching animal or human threats prior to their interception of the trespasser.

Specifically, livestock guardian dogs such as the [[Kangal Shepherd Dog|Kangal]] use loud alarm barks as a first line of defense against presumed threats; if these do not deter a perceived foe, other displays, such as bluffing and charging, are employed. For livestock guardians, proactive forms of defense such as biting are only used if all other forms of deterrence fail.

If the risk is from human intruders, a suitable dog can be trained to be aggressive towards unrecognized humans and then tethered or enclosed in an area that the owner wishes to protect when he is not around (such as at night).<ref>{{cite news|url=https://www.nytimes.com/2011/06/12/us/12dogs.html|title=For the Executive With Everything, a $230,000 Dog to Protect It|first=John|last=Tierney|newspaper=The New York Times |date=11 June 2011|access-date=3 May 2019}}</ref>
