As with most domesticated species, one of the first and strongest effects seen
from selective breeding is selection for cooperation with the breeding process
as directed by humans. In domestic dogs, one of the behaviours that is noted is
the abolition of the pair bond seen in wild canines. The ability of female
domestic dog to come into estrus at any time of the year and usually twice a
year is also valued. The amount of time between cycles varies greatly among
different dogs, but a particular dog's cycle tends to be consistent through her
life. This also called in season or in heat. Conversely, undomesticated canine
species experience estrus once a year, typically in late winter.
