I agree with others I would go with my heart. Also agree kennel cough is like a cold in humans and treatable. Georgie had a congenital spine defect that we didn't know about until he was 6. I know God gave us Georgie for a reason. He had surgery in September of last year and is doing amazing! He is actually better then he ever was. I am sure your furbaby will be just fine and you will be so happy that he is yours
