Tell the Vet About Desert Travel: Canine Valley Fever

Tell your veterinarian where your dog has traveled if an unexplained illness is not resolving. A desert trip can matter even when the dog is now being examined far from that region. Give the itinerary and dates rather than assuming the local clinic already knows about the exposure.

The University of Arizona’s Valley Fever Center for Excellence specifically advises reporting travel through affected regions when a dog becomes ill elsewhere. Valley fever is acquired by inhaling fungal spores from soil; it is not an infection the dog catches from another dog’s cough.

Bring locations, dates and the whole pattern

Keep a short record of places visited, time spent there and when signs began. Tell the clinician about persistent coughing, fever, weight loss or other unexplained changes, along with previous tests and medicines. A report that symptoms began after travel is a clue, not proof of Valley fever.

For example, “a week visiting family in Arizona, then a cough that has not resolved” supplies more useful context than “probably kennel cough.” The veterinarian still needs to assess the full history and the dog in front of them. Breathing difficulty or marked illness needs urgent care, not time spent perfecting a travel diary.

A positive test does not stand alone

The Center explains that an antibody titer can help with diagnosis but that other testing is often needed. Bloodwork, imaging and the clinical picture may all contribute. Ask what the result supports and what it cannot establish by itself.

Bring copies of previous laboratory reports rather than only saying that a test was “high” or “positive.” Keep the date, laboratory and result together. If another veterinarian reviewed the dog during the trip, arrange for that record to reach the current clinic.

Keep follow-up tied to the diagnosis

If Valley fever is diagnosed, obtain the individual treatment and recheck plan. Do not shorten medication because the dog appears brighter, or choose a food or supplement as a substitute for the prescribed care. Report problems with eating or taking medicine so the team can adjust the plan appropriately.
