I waited for 12 weeks to get sawyer, and watched his progress on the computer the whole time. When I went to get him, he had a bad cough. The breeder told me it was a reaction to his bordatella shot, and offered me another pup. I was so in love with this little fart by then, that he was all I wanted. I took him to the vet, and he was on antibiotics for about a month. He is doing great!! Kennel cough is pesty, but as long as you watch out for pneumonia it is not fatal. I thank God every day that I took Sawyer, cough and all.
