Fatcakes,
Fish oil is great – I would keep him on it for a while. You could also try a fish-based food for the sake of rotation and varying the protein intake. Lamb is good for skin and coat too, I hear.
As far as fiber, my pup is currently on a mix of Dr. Tim’s Grain Free (4.5% fiber), Nutrisca Chicken and Chickpea (7% fiber), and Vets Choice Holistic Health Extension Grain Free (5% fiber). He, however, suffers from hard stools, as high in fiber as his diet is, so kind people in this forum have recommended pumpkin and flax for him, and maybe even yoghurt – they are all good additives, and the latter REALLY seems to help him. All the foods he is on currently are 5-star rated (except for the Vets Choice – that is 4.5 stars I think) and grain free.
I am switching him to Earthborn Holistic Grain Free mixed with Vets Choice, and Victor Ultra Professional Grain Free mixed with Back to Basics after. All of that will have even less fiber than he has in his food now, but I will be adding the pumpkin, flax, and yoghurt daily, I don’t mind. I really like Victor and can’t wait to get Bruno on it, and they also have a salmon-based grain-free recipe. It is also very affordable and 5-star-rated.
That is for the fiber. As for the dandruffy-ness of your guy, I can just share my experience, and it is that my pup, when found, was so flea-infested, the vet had said she hasn’t seen a case this bad. He has had skin sores and wounds all over. With much TLC, grain-free food and daily fish skins (I used Beams by The Honest Kitchen), his skin healed up completely and coat is super soft and shiny. So this is why I may consider more fish in his diet, plus, I am sure more knowledgeable people in the forum will chip in with more advice.
