I am having a similar situation with my puppy who was just spayed on Tuesday (2/27). She was really slow moving and whiney and just wanted to sleep all the time. Also he bark was very hoarse, i'm not sure if that's what you mean by her throat seeming to bother her. Now 6 days after surgery she's still a little sleepier than normal but she does play and eat normally, and slowly but surely she's getting her bark back. Keep me posted on your little one, i'm sure she'll be fine while you're away. It's so funny you sound so much like me, all i ever do is worry, i must call the vet at least once a week.
