It was Dublin.
From Dublin SPCA:
Meet Digby, he is the 83rd horse our inspectors were called out to last week alone. Digby was found wandering on the main road beside Citywest on Friday. He is not microchipped so yet again we have no way of tracing his owners. Our vets are currently looking into the the reasons for his skin condition and we will let you know as soon as we have an update.
We need your support to help horses like Digby, simply share his story to raise awareness of the importance of traceability or you can donate online to help with his care.
