T thank you!!You can try flushing his nostrils out with water but you’d want to position his head tilted to the side so the water goes in one and out the other instead of water boarding him - having a nose full of maggots is probably not making breathing easy in the first place, you don’t want him inhaling anything.
I’d also suggest you continue to use the thread youve already started about his attack for further updates and questions. The people who’ve answered and helped you there will get notifications that you’ve posted again and will be able to continue to help. New thread each time might go unnoticed.
