Have had our 3 yr. old yorkie two weeks. Have taken her in twice already to the tune of $350 to find our why she smells. Last week it was an ear infection, this week it is yeast infection. Spent $40 on shampoo, that doesn't seem to work and am not giving her two medications. Has anyone ever had something like this and how long does it take to cure, or is it a lingering thing.
