So sorry to hear this. It's been 9 years minus one day since I had to say goodbye to my little Remy poodle, and I still tear up thinking about it. You & John both will be in my thoughts.
I am so sorry for your loss. It's been just over a month since we lost our "Sam"....I still look for him to be at the door when I get home sometimes....know that my heart is with you in your time of sorrow.
I'm so, so, sorry. I know how you and John treasured Rain. Rain was so fortunate to have loving parents. Words, at a time like this, are small comfort but please know you are not alone.
