I found Billie 6 years ago frozen to a footpath. He has always been very deaf and I always thought that this might have led to him being abandoned. He has no interest in playing ball now but still loves going out. However he does now seem to feel the cold in his head/ears.
There is no inflamation where he has lost hair, in fact it is very white and clean.
The incident happened when he was actively running after his ball as normal and his legs went from under him and he appeared very confused as to what was happening.
