Rare today even in Western Montenegro, the Budvanski Molos is a water loving mastiff, often seen aboard fishing boats and trade ships in the past. Its tail is sometimes docked by fishermen to prevent the dog from accidentaly knocking equipment overboard when excited, but this applies only to working dogs. Intelligent and friendly, the Montenegro Water Dog makes a good companion, but needs some socializing due to its somewhat confrontational nature around other dogs. The head is large and round, with a slightly narrower muzzle than other Balkan Molossers and somewhat longer ears. Straight-backed, deep-chested and well-boned, the Budvanac is a resilient water dog.
The waterproof coat is dense and of medium length, coming in shades of cream, fawn, brown and black, almost always with white markings of various sizes, usually on the head, chest and feet. Brown-coated dogs can have flesh-coloured noses. Average height is around 24 inches.
