Well apparently the Innova EVO has the Omega 3 in it already. But I do think I will try the Arctic Vigour. I feel so bad for the poor pup and his itchy, dry skin.
Thanks everyone for your advice. I'm glad it's not food allergies. His stools are nice and solid. Only a few loose ones, but that seems to be when we have him out of his orient, like at a friends house or something.
I'll update later once I try out the oils. THANKS!
