She has been awake now for almost 5 hours and has only coughed mildly (not wildly/frantically like yesterday) 4 times. She's been running around, acting like a typical puppy getting into mischief. I can't imagine that it resolved itself so quickly, but somehow, she's a LOT better! I'll probably still take her to the Dr tomorrow, but I'm so happy she seems better. Maybe it's the switching her to better food, maybe it's because I started her on vitamin C yesterday...whatever the case, she's not over it, but she's dramatically improved. yay.
Also, I'm thrilled to report that she barked for 2 (yes two) minutes in her crate last night and then proceeded to sleep for 6.5 hours. Life is seeming much better to all of us here today, haha.
