A. I would recommend to take her to your veterinarian for a check up. She may need diagnostic work up to understand if the signs you are describing are related or not. She may need blood tests done and radiographs of her chest to start with. Sorry not to be more helpful but the signs you are describing would need a very long discussion and the possibilities are several. I am available to discuss it more extensively in a consultation if you like.
