The Mioritic stands about 65–85 centimetres (26–33 in) tall at the withers and weighs 50–65 kilograms (110–140 lb). This massive dog is covered in thick fluffy hair. It may be white, with or without pale grey or cream patches, or cream or pale grey all over. The dog should have a "vigorous" appearance. Sexual dimorphism is evident in this breed, with males being significantly larger than females.
This Mountain dog has discipline as one of their main characteristics. It is a calm and well-mannered dog. As this dog was used as a herd protector, he is very attached to family and goes all the way when protecting those he is attached to. Because of this dog's ability to bond strongly with his master, training should only be started once the Mioritic puppy is already accustomed to the owner/trainer.
