I am a paramedic (not a vet) but to me purple or blue means that oxygen is not getting to the cells. It could be due to lack of circulation (massaging the ears could help with this) an infection (in which in this case the infection can cause a mild isolated septic shock and shunt the blood away from the tips of the ears this is not as bad as it sounds) As far as the doggie info im not sure, but this is normally the case in humans. I hope this helps and if not i hope your little one gets better. |
