I agree with both other responses, a second dog - whether it is
intended to be a new playmate for you or your Oliver, is a wonderful
idea. Many of the pups (at least half) we place into homes are
the second (or even third) dog, and all cite wanting a playmate
for their existing pet(s) as the reason. Without fail, if you take
certain precautions, it works to the benefit of EVERYONE. DO plan
to spend some extra time with your pets. You must make your original
pet feel "part" of the welcoming process and not as though they are
being supplanted by this new little "intruder". Encourage them to
play together and sleep together - and do NOT tolerate any signs of
aggression by either of them toward the other.
We often find ourselves placing our Maltese into homes where the
family has an ageing Maltese (or other breed) and they feel that
by having a new pet "in place" it may help to ease the sense of
"loss" of the older pet. Bringing a new pup into a home where the
existing "king or queen" has dominated the household for twelve years
or longer can indeed be a challenge but we've always seen it work
out in the end - we credit the perseverence of the owners but,
mostly we credit the charming and endearing qualities of the Maltese.
Good luck and let us know of your decision AND the outcome.
