My new pooch Sadie was spayed almost a week ago, just before we got her. The past two days she has started hacking and coughing, not all the time but probably 6-8 times/day and once she starts it seems very hard for her to stop. Her breathing gets laboured and sometimes she seems to hack something up, then lick and swallow. Could she be getting hairballs from licking herself more since the surgery? What else could be causing this coughing and what can I do to help it? I scheduled a vet visit for her before this started, but it's not for another two weeks and now I'm wondering if I should try and get her in earlier...

Any help would be much appreciated! I had dogs as a kid but this is my first "adult dog" on my own and I want to do this right!
