Here's a copy of the email that I received.
Any suggestions are appreciated.
I've also included one of my favorite pics of Molly from before the hair loss started. She loves her kitty.

Here's the email:
Wendy,
Can you post this for me?
Molly is a 5 yr (almost 6 now) old Basset. She has been very healthy. She had been eating Lamb & Rice food until Dec. 2004. That is when I decided to start her on a weight management food.
Feb. of 2005 I noticed a small balding spot on the scruff of her neck.
Her coat was always really nice and thick.
I thought maybe she was shedding out. I took her to the vets in the Spring for her annual shots etc. Other than the vet saying she needed to lose about 7lbs, he thought she was very healthy. He contributed the hair-loss to a strange winter and wet spring and that he had noticed many dogs shedding differently this year.
Well, she continued to "shed" all summer. I took her to the vets in November. Her body can't handle the yeast production, so she is on meds for that. Her blood work came back negative for Hypothyroidism and they don't think it is Cushings. We will finish the medication that she is on now, then try to decide if it is food allergies. The hair on
her whole torso has thinned so much that you can see her skin. Any thoughts?
