These dogs are the size of my dog lily who is a jack russel beagle mix. This dog is the perfect dog for old people who need a small gentle dog who is loyal and nice to people . It is a great dog to go on the plane. This means that people who travel around the world and visit family you can share the trip with you .The dogs are hardy that are 8 to 10 inches tall with the weight of 6 1/2 to 13 pounds. These dogs live 15 years of age so they will grow up with you and love you like your husbund but the difference is that he or she will not leave you for someone younger than you!!:)These dogs developed in Italy . They were royal all around the world!
