You have my deepest sympathies over the loss of your Bud.
Time will heal the deep pain from no longer having your Bud around and hopefully soon the memories of the good times you had with him will give you comfort. Bud is now all healed and flying free at rainbow bridge with all our departed little friends. He will forever live on in your heart.
Rest in peace, little Bud. You were much loved and will be missed.
