My 4 year old JG has been gasping alot lately. She's good weight, no worms, no bugs, no cold or snot. Just some chalky looking stuff, seems like you can scrape it. I tried to pick at it, I had her in a towel on my lap, but then her comb and hackles start to get dusky. I just don't know what this is, and if I should be digging around in her nose. Any ideas?
