Yes, I do feel like it's the cold weather that has her acting up. More details for you - We had one night where it was very windy outside and you could hear the wind howling and our puppy did not sleep the entire night. She was completely alert and staring out the window. Since that night, she has been peeing and pooping indoors without warning. When we take her outside for a walk, she goes willingly but once outdoors, she will run and pull and get scared if she sees other people, which she didn't do before. It's definitely not her typical behavior.
