A week ago, our beloved 5-year-old, Shamrock, died suddenly. One second he was bounding happily across the back porch. The next second, he was collapsed on the kitchen floor. He had what appeared to be a brief seizure and then was gone. His body went instantly limp. Although we rushed him to the vet, we pretty much knew there was no hope. The vet suggested it might have been an undiagnosed heart condition. We are just so heartbroken. Shamrock was such a gentle soul. Not a mean bone in his body. I used to joke that he was a Buddhist monk trapped in a dog's body. And now he's gone. Although there's small comfort in knowing that he didn't suffer, I regret not having had an opportunity to say a proper goodbye. I regret the tomorrows we won't have the chance to share together. My husband and 2 daughters seem to have rebounded far better than I have. Maybe that's because I was the one to walk him and feed him. Mine was the desk he curled up beneath while I worked. We still have a 2-year-old Golden, Blarney, and I'm trying to shower him with love and attention...but the loss of his dear older brother is so difficult for me. Not looking for speculation as to what the cause of death was...just support. Many thanks to those out there who respond and understand.
