This group of breeds is made up of those dogs that weigh between 15 kg and 24 kg. The estimated height for the dogs that make up this segment is between 30 cm and 40 cm.
Medium dogs are the most accepted because they adapt to living in widely spaced places and in urban areas. Pets in this group are quite controllable and do not require excessive care.
It is important to clarify that like the dogs of large and giant breeds, this requires a high degree of socialization. Many scholars of the subject claim that the potentially most dangerous breeds fall into this category.
