In the middle of the night our dog started coughing pretty loud, I thought she was about to vomit from the way it sounded. It seems to be getting more frequent. It is loud and dry and she does look like she is going to vomit, but nothing at all comes up. She's acting normal otherwise. Any idea what's wrong, or anything to help her feel better?
She is only 3 and has seemed healthy. About 3 weeks ago, we took her in to get her teeth cleaned. She had some problems after that, peeing in the house, like it just leaked everywhere and would squat without peeing a lot outside. We went back to the vet, he checked her urine and did an x-ray and found nothing and she got back to normal. I'm assuming that is not related, but we've spent a lot on her recently, so I really don't feel like paying for another trip to the vet. Other than that last vet visit two weeks ago, she hasn't been around other dogs recently, except my mom's, but he isn't sick.
