British researchers found that the process of puberty in dogs can be accompanied by behavior problems and attachment disorder to the guardian, the same as in humans. It turned out, for example, that those females, which are less tied to the owners the first estrus occurs much earlier than the average in the breed, and at the age of eight months (approximately puberty dogs) puppies cease to obey commands — and mostly from owners, not from strangers. About it write the scientists in Biology Letters.
Due to the active work of hormones and related changes in the organism of human behavior in adolescence can vary greatly: children become more conflictual, and they have, for example, often manifests itself in risky behaviour. The relationship between behavioral factors and early pubertate apparently reversible, puberty faster occurs in adolescents who are less attached to their parents and, in principle, often going with them to the conflict — even as a child.
Lucy Asher (Lucy Asher) from Newcastle University and her colleagues suggested that sexual maturity of dogs is the same scenario and is also subject to the relationship with the guardian — a man. First, they decided to evaluate, how is the age of puberty in dogs and their attachment to the host, and interviewed for the owners of 70 bitches. Study participants answered questions about their prefer their Pets to sit closer, being puppies, and just as hard whether they were transferred to the separation.
Indicator of attachment to the host correlated with the age of puberty — namely, the onset of first estrus. Puppies that are five months in age (the average age prepubertatne for dogs) were less attached to their owners, estrus occurred significantly earlier than the average is typical for their breed (p = 0,0004).
Next, the researchers followed-up from age (and, accordingly, a certain period of maturity) dog depends on whether it becomes more manageable. To do this, scientists have tested how dogs (females and males, 93 puppy) obey the command “sit” in five months, and then in eight months (that is prepubertatne and puberty) age.
In adolescence, dogs rarely obey commands, but only in the case when the teams gave their owners, not strangers, and in prepubertatne five months of age, this was not observed (p = 0.044). According to the authors, this is consistent with the data, which were obtained in the study of the effectiveness of training and its dependence on age: the most disobedient when training was just eight-dogs-adolescents (p = 0.001). Questionnaires filled in by the dog owners, also pointed to the fact that behavioral problems in adolescence Pets were associated with less attachment to the host (p < 0.001).
The long process of domestication allowed the dog comfortable to get along with people and even to become a full member of the host family. This, as shown by the authors of the new work has also brought negative consequences, making the behavior of a growing puppy problem — somewhat similar to the behavior of growing children. However, the researchers clarify what is the behavior as adolescents transition to adulthood, provisional, and sure is faster than in children.
In General, to correlate the age of the dog with the person’s age (for example, to see whether they have reached already puppy puberty) not so easy, but last fall scientists have devised a fairly simple formula.
