symptoms of canine fever
Canine Valley Fever Symptoms. The symptoms of canine valley fever in dogs do not usually start to surface until about three weeks post-infection. The exception to this rule would be dogs with extremely compromised immune systems, as well as puppies. In these situations, the symptoms will probably develop rapidly and can lead to a questionable health situation. Under normal conditions, the symptoms will only be related to some mild respiratory annoyance. 1  Some of the more mild symptoms of canine valley fever include: 2  Continuous hacking cough, sometimes producing phlegm. 3  A temperature higher than 102 degrees Fahrenheit. 4  General fatigue and tiredness. 5  Decreased appetite.
