I know the feeling of having to send a doggy over the rainbow bridge and it's absolutely heartbreaking.
Hopefully the fun memories and pictures you have of your beloved friend bring you comfort. And know that you gave him a wonderful life and he loved you more than he loved himself.
And as for the rest of your week, who is better than you?! You are rocking this first week of May and I was so happy to read all the good stuff! I was never so happy to send the month of April into the distant memory. Keep up the good work, you are doing awesome. And good luck with the new job!
