Hi,I have a Dobermann aged three. She has had skin/coat problems for about 18 months now, She has had several tests including blood tests for thyroid but all to no avail. I was actually on the net one day and came across a food which is called 'James Wellbeloved' It is a dried food and you have to try this for a minimum of 6 weeks, Aysha is on her 2nd week & I think she is improving. Her coat is very thin in patched and she has smalll lumps associated with the proble. it might be worth a try but I'm all for trying. the food is available in most pet shops if not from your local vet.Let me know if you tey it or if you have found out something else about the problem
