West Highland White Terriers

Hi , Im new to this, nut our westie has terrible skin problems, and in the past ear we have spent over 2,000 dollars in vaccinations daily, or ones that every other day, it goe on and on. We just cannot continue to do this-spend this money and fee us as well. Do ya'll have any ideas, or has anyone had any problems similar?. We bathe hi 3 times a week with otmeal and then the leave on lotion from the vet .....Nothing. He is 4 and he as always had these problems antibotic helps, redinosone cleasr them up. I have been told if we keep his anal glands cleaned, or aqueezed twice week will work, but it sounds like vodoo vetanarian.. Anyway we have tried all foods zd , dd, everything. The vet gets kickback on everything they sell.

ANY HELP would be appreciated dave.. thanks from Bama
