I also waited a while after my last yorkie passed away.
But it was because I lived in an apartment that won't allow dog, my job required me to travel constantly, and I was in school and working full time.
So timing wasn't right for me.
But now that I have Momiji, ohhhh my life is complete. (almost.. I wish I can find a husband... but that's another story...)
You will never forget your Mogli but you will build a history with Benny.
It will be good for you.
Bad things happen for a reason.
Please keep your spirit up and enjoy your new baby.
