Ddog2 has a musty/corn chip smell that I recognise from my old lab and think may be a yeast infection. I took her to the vet last week (before I had noticed and identified the smell) and she got a clean bill of health. Her ears are clear but she is slightly more itchy than usual. When my lab had this her skin became very red and sore, the vet recommended Malaseb (?sp) shampoo and the lab had injections for allergies which helped and possibly a steroid injection to help with the itching (not sure about this as it was some years ago). Ddog2 is not at the stage and I wondered whether there were any supplements that I could give her or something I could do to prevent this escalating.
