Thanks so much for the tip on google regarding dogs coughing. There is a lot of great information and settles my nerves knowing that what I read fit my dogs condition. I did take him to the vet three times and found the kennel cough to be most like Soki's condition and the doctor could not find anything wrong. His energy level and eating habits are the same.....Thanks so much for the peace of mind. Great Site...I have marked as favorites...Thanks again Enoel.
