Why was your dog strange?
She was the kindest dog to humans, but would attack any canine, even a puppy (we got kicked out of the dog park). She wasn’t very bright, and was almost untrainable, but a sweetie to all but dogs. She went blind early in life, but could sense a body of water whenever we neared one and would throw herself without reservation into the water and swim like a retriever. I had to keep her on a long leash when she went swimming. Could not train her to walk without pulling on a leash. Interesting dog.
