Valley Fever, or Coccidiomycosis, is a fungal infection that invades humans as well as our four-legged friends, and it can be especially dangerous for dogs. Since the fungal spores that cause Valley Fever live in Arizona’s dust and dirt, it’s a serious issue for Phoenix pet owners with the highest rate of infections happening in June and July.


Symptoms of a Valley Fever infection can range from a harsh cough and lethargy to seizures and even death in those with weakened or underdeveloped immune systems. However, if caught early, it is treatable with proper vet intervention. It’s important to familiarize yourself with signs and symptoms.


Valley Fever is extremely hard to prevent as the spores are just about everywhere in Phoenix (in fact, many humans are infected without showing any symptoms). It can also be difficult to pinpoint as symptoms don’t typically occur until a few weeks after infection and have a wide range of severity.
