We have the same issue also ! 6 month knot English cream retriever it’s horrible ! Like it snows in our house minute by minute where ever she walks ! Any advice ? We also a have tried it all!
My 11 week old golden puppy has it. Of course the vet ruled out cheyletiella mange but offered little other explanation. A seborrhea or possibly ichthyosis are his thoughts and to give it time to see if it goes away. I am brushing twice a day, giving salmon oil, bathing once a week in oatmeal shampoo. He is happy and doesn't scratch much. No redness, loss of fur, but lots of white flaking skin. Mostly on his chest and sides, but also some from his back. None on his belly where there is no fur. I just switched him off chicken to a fish only diet. Any other ideas? Maybe he just has to outgrow it.
