ANSWER: This is
Normal Behavior between dogs
kept in back yards next to each
other. Many, many dogs
do it with the neighbor dog(s).
It is a game to them. Do not
forget that "Hereditarily" they
are Pack Animals. They roar up
and down the fence line,
sounding "Oh So Fierce", but it
is a game. Dogs love us as
their HUMAN PACK MEMBERS, but
socializing with another dog is
a "Neat and Great Thing"!!!
Your puppy is just now
starting to reach MATURITY,
both Physically and
Mentally. Just Starting!!!
This game is OH, SO MUCH
FUN!!!
What I tell people (If They
are Good/Close Friends With
That Neighbor), is to let
the dogs play together on a
daily basis. Both dogs get
much needed SOCIALIZATION
out of it.
Rarely though are we close
enough, personal friends
with the neighbors to let
this happen.
So, discipline him gently
about his great JOY of this
what I call, "FENCE RUNNING"
or Let it Be? The secret is
to give both Fence Runners
more contact time with their
humans and more Exercise out
on walks from the
backyards. Give your own
pup/dog more things to do,
to fill his days with
happiness and he won't have
to resort to "All Out Fence
Running" for something
exciting to do!!! "More
Time Spent", especially
Hands On Training
Time with YOU daily (I
repeat daily), and
he won't need to socialize
as much with the neighbours
dog???
