[NAGDU] Red ear

[Tracy Carcione]

When I took Krokus to the vet yesterday, she said one of his ears is a bit
red inside.

I am wondering how I could know this?  His ears don't smell, and they don't
feel gunky.  The vet said they were clean, but one still needs treatment.

I guess I can have a neighbor or co-worker look at them occasionally, but it
would be simpler if I can figure out there's a problem on my own.
