Not strangles-- other options?
Hi everyone-- I went to check on my mare today and she has bilateral nasal discharge that started milky white and some clear and turned a little greenish after she was worked for approx 10 min (walk/trot). She often has clear discharge when the weather is exceptionally hot or cold so I wasn't concerned at first but then I also noticed that her submandibular lymph nodes were also slightly swollen--two distinct swollen lumps that were not tender. Upon trotting she had to stop to get out a singular throaty cough. She has been exposed to strangles in the past and never gotten it-- besides she's far out of the normal range for that now. I would suspect an upper respiratory infection-- but are there any other thoughts? I called the vet and they agree that without temperature we can wait a few days before coming out.
She's still eating, drinking, defecating and urination normally. Still energetic, etc. Last vaccines given late June of this year. I will be checking her temperature tomorrow, I couldn't find my thermometer today :/
