Timing is only a question you can answer. My beloved dog, Gordita, died not quite two years ago. Before that, I'd always maintained I wouldn't be able to pursue getting another dog til after my grief had subsided.
I'd presumed I'd need an adjustment period, as her death would likely annihilate me emotionally. I questioned whether my beleaguered heart would be ready to love another.
But: I ended up getting my dog Anabelle right around the time of Gordita's' demise...And while she in no way replaced Gordita, her lively antics and dog sugars did prove a balm for me after Gordita passed away.
Just as with our spouses, there's just no way to accurately predict what will help or won't until after the (sad) fact.
