Debis in Nostril??

Hi there,

I had a little mishap trying to leash train today, went great until he got a little nervous and started running all around the cage. It was too loose so one side of the adjustable harness slid down and pressed his front right leg against his body and he hind of wiggled through his cork hide his like that. Scared the hell outta me, but quickly got him out of it and I think he's fine. I did notice that he had a little bit of char on his face (from the inside of the cork hide) and then I noticed maybe a little black speck up his nostril?? Will he be okay if some debris got up his nose?? Anyways, now I'm worried about that. Also I checked his front right leg like a million times and I don't think the leash/harness hurt him. Leash training will now take place in a bin with no obstacles

Here is the nostril with potential debris:

Leave it be, if it's bothering him he'd be sneezing or scratching at it.
It's come out eventually naturally.

Thank you, good to know he would scratch or something. He seems to be doing just fine : )
