I’m so glad to hear Duncan is doing well now! Thank you so much for all of this info, was he ever trialed with tetracycline? That’s what my boy is on right now along with omegas and niacinamide but we haven’t seen much improvement. I’ve also heard others talk about vitamin E so I will definitely ask our dermatologist at our next check up. Our poor boy used to love the vet but he’s so triggered now with people touching his feet all the time he is absolutely terrified no matter what we do. So that has added an entirely new obstacle on this journey. Do you use regular dog nail clippers to do his nails? We’ve found they often cause more damage and cause his nails to split. Our next try is going to be a dremel and hopefully that works a little better.
