Dogs that spend a lot of time outdoors, especially digging or sniffing in dusty soil, are more likely to inhale the spores.Weakened Immune System:
Dogs with compromised immune systems may struggle to fight off the infection once exposed.Breed Predisposition:
Some breeds, such as Boxers and Doberman Pinschers, appear to be more susceptible to severe cases of valley fever.Age and Health Status:
Older dogs or those with pre-existing health conditions may experience more severe symptoms.
Understanding these risk factors can help you take preventive measures to protect your dog from exposure.
