My dog is coughing and hacking like he's trying to throw up. Is it kennel cough?

This sounds like he may have an upper respiratory condition. This could be something as common as kennel cough, especially if you take Bakster to dog parks or if he has contact with other dogs. Usually, kennel cough is self-limiting, ie goes away within 3-4 weeks without treatment. It is caused by a number of different virusesw and bacteria, the most well-known being Bordetella bronchiseptica. Treatment is only necessary if the coughing get s excessive, and/or Bakster gets a fever or otherwise appears ill. You should take Bakster to a vet for an exam if he shows any signs of breathing problems, lethargy, not eating and/or drinking. Treatment for upper respiratory disease consists of cough medicine and antibiotics if indicated.
