Dogs and All about Them

Nor
are
their
habits
different.
The
wolf's
natural
voice
is
a
loud
howl,
but
when
confined
with
dogs
he
will
learn
to
bark.
Although
he
is
carnivorous,
he
will
also
eat
vegetables,
and
when
sickly
he
will
nibble
grass.
In
the
chase,
a
pack
of
wolves
will
divide
into
parties,
one
following
the
trail
of
the
quarry,
the
other
endeavouring
to
intercept
its
retreat,
exercising
a
considerable
amount
of
strategy,
a
trait
which
is
exhibited
by
many
of
our
sporting
dogs
and
terriers
when
hunting
in
teams.
A
further
important
point
of
resemblance
between
the
Canis
lupus
and
the
Canis
familiaris
lies
in
the
fact
that
the
period
of
gestation
in
both
species
is
sixty-three
days.
There
are
from
three
to
nine
cubs
in
a
wolf's
litter,
and
these
are
blind
for
twenty-one
days.
They
are
suckled
for
two
months,
but
at
the
end
of
that
time
they
are
able
to
eat
half-digested
flesh
disgorged
for
them
by
their
dam--or
even
their
sire.
We
have
seen
that
there
is
no
authenticated
instance
of
a
hybrid
between
the
dog
and
the
fox.
This
is
not
the
case
with
the
dog
and
the
wolf,
or
the
dog
and
the
jackal,
all
of
which
can
interbreed.
Moreover,
their
offspring
are
fertile.
Pliny
is
the
authority
for
the
statement
that
the
Gauls
tied
their
female
dogs
in
the
wood
that
they
might
cross
with
wolves.
The
Eskimo
dogs
are
not
infrequently
crossed
with
the
grey
Arctic
wolf,
which
they
so
much
resemble,
and
the
Indians
of
America
were
accustomed
to
cross
their
half-wild
dogs
with
the
coyote
to
impart
greater
boldness
to
the
breed.
Tame
dogs
living
in
countries
inhabited
by
the
jackal
often
betray
the
jackal
strain
in
their
litters,
and
there
are
instances
of
men
dwelling
in
lonely
outposts
of
civilisation
being
molested
by
wolves
or
jackals
following
upon
the
trail
of
a
bitch
in
season.
