I have swopped 3 BCs over to a raw diet and they have been on it for about a month now. My eldest is 8 and is crossed with a springer. He suffers from dry skin and quite often got sore patches. The sore patches have stopped since being on raw but his dry skin suddenly seems to have got worse. Somebody has suggested that this is his body going through a detox and it should clear with time. Is this right?
