I am STILL looking for a USP approved fish oil with a good amount of DHA and EPA for Ellie.  LOL. I think I gave up.
 
I'll see what Ellie's vet thinks about probiotics.   
We'll probably skip the glucosamine for now (unless I start to worry about her knees

). 
Nicole, do you know that dogs in Roxy's line?  I'm convinced they're at least distance cousins.
