We had to put Sam to sleep today. He couldn't hardly walk, was very wobbly, was mostly deaf, and nearly blind. Last summer he woke up from a nap on his rug here in the house and was very disoriented, head and eyes going back and forth. He was Ok after about 10 minutes. Yesterday he was doing it again and also today. I asked the vet if it was a stroke, and she said no. It was something with a long name that I can't remember. She could see his eyes doing it today. His rear legs or hips couldn't hold him up anymore, so it was time. He was a good dog.
