Dogs and All about Them
·
Robert Leighton

The
foregoing
chapters
have
given
abundant
examples
of
how
the
various
breeds
of
the
dog
have
been
acquired,
manufactured,
improved,
resuscitated,
and
retained.
Broadly
speaking,
two
methods
have
been
adopted:
The
method
of
introducing
an
outcross
to
impart
new
blood,
new
strength,
new
character;
and
the
method
of
inbreeding
to
retain
an
approved
type.
An
outcross
is
introduced
when
the
breed
operated
upon
is
declining
in
stamina
or
is
in
danger
of
extinction,
or
when
some
new
physical
or
mental
quality
is
desired.
New
types
and
eccentricities
are
hardly
wanted,
however,
and
the
extreme
requirements
of
an
outcross
may
nowadays
be
achieved
by
the
simple
process
of
selecting
individuals
from
differing
strains
of
the
same
breed,
mating
a
bitch
which
lacks
the
required
points
with
a
dog
in
whose
family
they
are
prominently
and
consistently
present.
