I am so sorry for your loss. I am also dealing with the loss of a beloved Yorkie less than two weeks ago and can empathize with the intense and overwhelming grief. I see something that reminds me of my Tykie and I am on the floor crying. Let yourself go through the grieving process.
I know it sounds silly, but someone told me that she used to "Blow kisses to heaven" and imagine her furbaby catching them. When I find myself crying, I "blow a kiss to heaven" and imagine my amazing and incredible furbaby getting them
Sounds silly, but it helps.
I don't think it's something we will ever get through, overcome or understand. They are truly a member of the family.
And at 14 weeks, that must make it so much harder for you. However, it just shows us how fast these little guys take our hearts and run with it
RIP JoeJoe.
