The reason I asked this question is that I had an experience. My father was gone a lot and asked me check in my mom every now and then. He had gotten her a GS for protection/companionship. I stopped by one day to check on her and she took forever to answer the door. The dog was very excited, and she seemed out of breath. She made some excuses to not wanting any company. The dog would not stop nuzzling her. Got me to thinking. I came to visit her some weeks later and asked how she was getting along with Rowdy. She smiled and said that they were inseparable I left it at that and never thought of it again until I discovered my interest in this many years after she had passed.
