Sunday morning our 14 year old black lab began throwing up, had no appetite and just wasn't himself. Each day this week he seemed to be slightly better until waking me up yesterday morning at 2 am and vomiting up the only full meal he had eaten since Sunday. Off to the vet we went expecting that he may not come home with us. The vet confirmed our fears, cancer, heart problems and possible kidney failure. We knew cancer was a possibility as we had a large tumor removed in the spring and chose not to have it tested due to his age. We also promised him no more surgeries. The vet sent him home with anti nauseants and painkillers so we can have a few days to snuggle him and bring him back tomorrow. The problem is now that he is medicated he is clearly feeling better and eating and making us question our decision even tho we do know things will get worse. It's just so hard to decide to end his life when you walk in the door to a wagging tail. Has anyone found a way to forgive themselves and come to terms with this? I feel like I'm murdering my best bud.
