Mr. Darcy in May, 2010 after being diagnosed with thyroid and cervical issues.  

Despite everything, he is still magnificent to me, and he still makes me cry when I look at him he is so beautiful...  
 
Here is an image of where he has developed a "rat tail" showing
hair loss around his tail area due to low thyroid.   He is not itchy
at all and doesn't have any hot spots or hair loss elsewhere on his
body.

He does have a rash that isn't itchy around his jowls and nostrils.
 We have been able to reduce this by having him wear a cloth bib
most of the time and making sure the area is washed several
times a day.   Tacrolemus has helped with his eye issues.
