Mal-shi
Mal-shi, also known as malt-tzu, maltzu, and malti-zu, are a type of designer dog resulting from a cross between a purebred Maltese and a purebred Shih Tzu. Most Mal-shi are F1 crosses, as there has been little interest in developing the dog as a breed. They are not recognized by any major kennel club.
Because they do not shed, mal-shis need to be groomed often. Sometimes this breed can also have some health problems because of their size, flat face, and small wind pipe. Some mal-shi suffer from malformed knee joints, known as patellar luxation, which causes internal friction and can eventually cause arthritis.
