I have seen kennel cough last for 4-6 weeks and it often took more then 2 different kinds of antibiotics and cough suppressents. The vet should have been able to hear if the lungs were clear. This dog is only 6 months old? maybe there is a heart defect?
Does the dog have difficulty breathing. Or has stopped being as active as it had been because it maybe getting short of breath? Does the gums get bluish in color?
If you see an enlarged heart ? investiage to rule out congestive heart failure? Is the dog urinating alright? |
