Rats! I wrote a long-ish response and now it's gone.
Anyway, Kaji and Morgan have those lovely soft coats. I think Kaji gets more dander and dust caught in his hair. I doubt it's seasonal allergies. I have allergic reactions all year long. Kaji also does not spend time outside. (he use to get 5 walks a day vs his 0 walks now) When I first had him, I was having some issues. I also bathed him more frequently since he had potty accidents back then. He would get soaked in pee sometimes.
He also sleeps right under my nose sometimes. It's a new behavior he's doing. I don't have the heart to have him move.
