I once woke up in the middle of the night and yelled something about my dog. I felt real panik, my girlfriend tried to calm me down. She probably thought I have a weird dream or something. I was so wide awake. She was so sure everything is fine. I told her she is probably right, but I have to look anyway. I just had to. When I found him he was laying on the side under a display. He was still moving his legs and his tounge was hanging out to the ground. He was breathing quite rapidly. I picked him up and put him on his feet, but he just kept walking and his tounge was still out. I put him in a box and watered his tounge and pet him for an hour. His legs were going and going, but he could move his tongue from time to time. Like he was annoyed by the water, he kinda scoffed and it broke his breathing shortly. I kept dripping water on his tounge and he sighed a few times. I felt horrible. Eventually he snapped out of it and looked at me exhausted of his ordeal, drank a little, licked my hand and fell asleep with normal breathing. He was fine the next day. I can not explain this, but this dog and I had an emotional connection that went through closed door, walls, stairs and even over reassurance of my girlfriend and the comfort of a warm cosy bed.
