In a very rapid (over the course of 48 hours) amount of time, our dear 4 year old German Shepherd, Guinness, went from *fine* to dead.
He was playing like his normal self on Monday, and by Wednesday night he was refusing to eat anything. We decided to take him to the vet first thing in the morning, and by that time, he was dead. We have no idea what happened - our other dog, Sammie, is fine.
While I often thought that Marley & Me was based on our trials with Guinness, at the end of the day he was still our dog, and we loved him.
We will miss him dearly.
