Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your wee one’s situation, and wanted to help.
Again I do apologize that my colleagues could not aid you sooner. If you would still like assistance, can you tell me:
How long ago was the attack?
Where on his body was he bitten?
Can he voluntarily move his legs
, since if he won't stand?
You noted that he has health issues, is he on any treatment for these?
treatments, since he is an older lad?
