We currently have 2 dogs, one is about 3 or 4 years older than the other. They are small dogs (@ 24 lbs and @ 14 lbs) but they are different breeds and quite different personalities. The eldest is definitely declining and encountering more and more health problems (eyesight, heart congestion, sporadic nipping/snapping, etc.). He does not appear to be suffering and regular vet visits do not raise concerns about this; the vets are confident prescribed meds are managing his conditions and not prolonging discomfort or agony.
I mention this because we know/see the end coming, but just can't say when. So we're looking at a gradually approaching horizon, rather than a sudden, brief downturn.
So then our question will be – do we NEED another “new” pet? Is one enough for us? Does the surviving dog need a companion? Do we enjoy the one until his time comes and we're faced with being “empty nesters?” OR are we setting up the scenario to start the cycle all over again?
