Dogs do have souls and they understand a lot more than we give them credit for. God Bless Hawkeye and his fallen master. They will be reunited again some day.
Our two canines KNOW when my husband is even thinking of going someplace in the car. I have no idea how they know, but they know. I first learn of the pending trip by their barks which are only used for a car ride. It’s more than the signals he sends and he doesn’t even have to send one. They know.
