Kennel Cough

When I went into the kennels for roll call this morning I heard a noise all people involved with dogs dread to here, a dog coughing. I checked all the dogs over and although there is only one coughing there appears to be a few who are below par as tonsils are swollen etc. I have separated them from the general population as best I can and fingers crossed it wont spread to all the dogs. It's surprising that the dog who is coughing hasn't left the yard for 2 months but he could have caught it off one of the saplings who went for schooling this week. Fingers crossed that its not too severe a strain.
