How can you tell if your dog has respiratory problems?

Last night my dog sneezed for 15 minutes, a sneeze about every ten seconds. Then I was thinking about how she does this snorting thing where she snorts for about 15 seconds (kind of what a Pug would do) and she has done it ever since she was a puppy and sometimes she does it when she is sleeping. She also sometimes just coughs. She is a Keeshond mix and when we got her she was 7 months old and she had Kennel Cough. Could she have respiratory problems, or are these things from her having kennel cough?

You should take her to a vet if you're not sure. Your dog may have an infection, like bronchial infections.Dogs also do two types of sneezing: Regular and reverse. This snorting sound may be the result of reverse sneezing.That being said, I've had a total of 6 Keeshonds and have been involved with Keeshond rescue. Our current pack is 3 Keeshonds and one Doberman.When we first got our fur-butts, I was startled at how much they pant and snore. Between myself, my wife, and the three Keeseys, my bedroom sounds like a lumberyard.Kees can make some of the most disgusting nasal sounds possible, and it's completely normal for them.Still, check the dog with a vet. If the sneezing is the result of an infection, you'll want to get on top of it as soon as possible.By the way, this was one of our Keeseys: http://www.youtube.com/watch?v=9N9f-i4dj6Y
