A shaggy dog that doesn’t shed (its polish name is Polski Owczarek Nizinny), the Polish Lowland Shepherd has arrived. It is a magnificent family dog with great affection for children. As an independent worker, it makes decisions for itself, and tests its owner regularly. It has an incredible memory and is very loyal to every family member. It shows much self control and is usually balanced when treating people and in its decision making.
An eight week specimen should weigh about 4 kg. As a puppy it is a teddy bear with no tail. Naturally, the future owner should take its time to learn about this breed, its structure and character, before making a choice. Besides their good health and structure, good temperament should be sought, avoiding nervous or aggressive puppies. The adult Polish Lowland Shepherd is suspicious by nature, reserved with strangers, but never fearful, and grows at a good pace. According to breeders physical maturity is placed over the 18th month. Adolescence is marked by undercoat growth and the coat color change. A character change from kind puppy to suspicious adult should be expected.
Once upon a time… and God created a perfect stuffed animal to watch over the herd. Nowadays Polish Lowland Shepherd has inherited new herds of fans to guide and adore.
Due to the fact that the breed is quite rare, and relatively recent in English speaking countries, there is little veterinarian investigation about it. According to the breeders and veterinarians in Poland, there is not enough evidence to draw conclusions about hereditary conditions. It seems to be subject to common problems that affect every breed, and that said diseases are more individual cases than specific to the breed. Naturally, breeders and owners should take precautions as for X – rays and checkups for progressive retinal dysplasia and hip dysplasia. Breeders in the US have observed some skin swellings and allergic reactions, for which the brushing is very important throughout the year. The Polish Lowland Shepherd can live 12 or more years.
Although the temperament varies from one puppy to the other, even a shy Polish Lowland Shepherd will make a charming company dog.
