Ever witnessed your pet die?

I remember one mid morning when a strange dog invaded our compound. It looked disoriented and fearless. Our dog went after the intruder and a fight ensued. We were quick to intervene and the strange dog vanished. I reasoned that it was a rabid dog and went into overdrive looking for a vet. He seemingly escaped unscathed but later, he had another complication and my granny killed him with a strong blow to the head. It took me a long time to recover from the sorrow e witnessing him die.
