One time I had Fiddle on my lap and I had some treats with me that I was giving her occasionally (Companion training) and my partner, who Fiddle loves! Came over to pat her and she went bananas! I could feel her growling and then get up and go full on savage beast attack lol! We are currently training her to not resource guard.
But it was quite shocking when it happened, she pretty much attacked her DAD!
