So, so adorable! And so sad about how her previous owners treated her. Why on earth do some people get dogs? Anyway, she will start a new, loving, stimulating life with you.
I have an extensive doggie capsule for my walks with our rescue dog. I wear things on walks I would never wear anywhere else (e.g., a bright tomato red North Face windbreaker, a baseball cap, a fanny pack sort of thing full of treats and poop bags....). I have specific shoes, jeans, boots, etc. for walking him.
