I just got my new boxer pup yesterday and I can't believe how much I already love her. I'm already sitting up at night like a worried mother!! At 2:30 AM here she woke me up to let her outside because she was whining like she needed out (she did). Got back inside and she was acting a little weird. Took her back upstairs and she started hacking. Almost sounded like she was going to vomit but her mouth was closed. Would open a little every now and then as if she was choking on something and couldn't get it up. I have no idea what's going on. I checked her mouth and nothing in there. Her poor little eyes looked like she was scared out of her mind. Gave her a little water and it seemed to stop. She was able to fall asleep but her breathing sounds a little off. It almost seems as if she has a cold (she was sneezing a lot earlier and now almost sounds as if she has a stuffy nose at times. Any suggestions? Should I make an emergency trip to the vet tomorrow to get all checked out? Am I totally overreacting and should just go back to sleep?
