We got Yoda when he was 8 weeks! Around 9 weeks, he started coughing. He has had three different antiobiotics. He just finished his last one this am. He is still coughing!!!!!!!!!! The vet has mentioned kennel cough, cold, tonsilitis, and pneumonia. They are not sure what it is. Has anyone had a dog to cough for this long? I am frustated that he can not get well!!!!
