Hey Deanna, I saw you'd posted about Peanut having some sort of pimples/skin issues so I thought I'd do a little digging on the net. I'd forgotten to show you the articles until I saw this thread pop back up. Now, you know what they say...sometimes TOO much info is a bad thing but I found the topic interesting enough to have a look around at different articles out there!
This first is about common skin ailments (Seborrhea in particular):

Here's one that discusses acne in a pup:

I'm really glad Peanut is feeling better!
