|Sprite showed a lot of energy the day he passed|
One of the questions I get often about pets and the afterlife is actually about their behavior just before they cross over. Q: Why do pets show a burst of energy on the way to cross over?
A: As I noted in my Pets and the Afterlife books, usually when dogs know that they are going to cross over - or their parents are taking them to the vet for their final goodbye, their adrenaline causes a surge of energy because they are happy and excited to move on out of pain.
My dog Sprite did that on his last day. In days leading up to that day, he could barely walk, his kidneys were failing, he had a very bad heart murmur, he was almost blind and the final straw was when a tumor burst in his nose (and we took him home for one more night with our other canine kids). On the trip to the vet he was energetic for the first time in many weeks and ate every treat we gave him (when he hadn't eaten food for days). So, they do show a rush of energy before they pass.
