Hello Robyn,
I am so sorry for the loss of your dog I know exactly where you are coming from with the love. I would like to tell you that each pet will be different, that your love for that pet will be just as deep but different. I hope that you will find your new furbaby, they make things so much easier to deal with.
I would also like to tell you that some people believe that God never gives you more than you can handle, but like you I wonder where he is now. It would be nice to know that he knows when we have had enough.
I don't pretend that I know the answers but I just wanted to let you know that you are definitely not alone and I would really like to get to know you better.
