One of the ladies on here has tremenous amount of hair on her standard and she was using fish oil with her dogs from GNC.
The ones from GNC do not smell like fish at all and I believe these are the same ones being used on Vaus. I used them and they have a lemon scent/flavor ( when you burp). I do not like fish so this is why I got those GNC ones for my self.I think I'm going to try and stay away from fish oil.. We have a couple dogs that come into the salon that get fishy foods and they smell like fish when you bathe and clip them.
I don't know if it's just when you feed them a fishy kibble, or if its fish oil.
