Canine chronic idiopathic rhinitis… one of those conditions that can make even experienced clinicians sigh a little.
Chronic sneezing. Mucopurulent discharge. Multiple treatments. Owners understandably frustrated.
A new open access JSAP paper (75 dogs) looked at how these cases were managed and what actually seemed to help.
A few things that stood out to me:
👉️NSAIDs as first line therapy were associated with improved outcomes
👉️Antibiotics were used in the majority of dogs… but weren’t associated with better outcomes
👉️Steroids helped some dogs, but responses were variable
👉️60% of dogs were coughing
👉️~20% had CT changes consistent with pneumonia
👉️Dental disease was present in over 90% on CT
So, a couple of practical reminders for cases like this:
❓️Think inflammation first,
❓️ Be cautious with repeated empirical antibiotics,
❓️ And don’t forget to check the chest and the teeth.
The good news? Most dogs did improve with management, even if complete remission was less common. Still a frustrating disease… but this paper gives us a bit more evidence to guide how we approach it.
