The Greek Shepherd or Greek Sheepdog (Greek: Ελληνικός Ποιμενικός, Ellinikós Pimenikós) is a Greek livestock guardian dog that has been bred for centuries for guarding livestock in the mountainous regions of the country. A Greek Shepherd might not be suitable for first-time dog owners. Like all livestock guardian dogs, they tend to be independent thinkers. These independent dogs need consistent training and intelligent guidance.
