My heart goes out to you, but now you know that Sammy and Louie are running and playing happily together at Rainbow Bridge. They will wait for you to join them when it is your time. Then it will be a wonderful reunion, full of smiles, tail wagging, tongue licking and lots of happy tears. Until then Walter will help your heart heal. He will not take away the grief after saying goodbye to Sammy, but he will help you smile again. It is so important to be able to find reasons to smile again, because at times it does feel like an impossible task after saying the saddest goodbye to our dear friends.
It will give some comfort to bring Sammy home again in a few days. I know that bringing Bella's ashes home with her family, where she belongs, helped to comfort me.
I agree, that our hearts are big enough to love many dogs. They each are different personalities and we build different relationships with each one. After we lost our beagle, Bella, we rescued 2 new family members, a springer spaniel X border collie called Charli and a chocolate lab X kelpie called Buddy, and we love them both so much. Our hearts still hurt every day because we miss Bella, and we always will, but Charli and Buddy have brightened up our lives once more and brought happiness back to a place where we were feeling very down.
Keep your memories of Sammy and Louie in your heart. They are yours forever...no one can take them away. I hope that those precious memories will soon bring you more smiles than tears.
