The dog came in for de-ticking but the main problem is chronic ear and skin infections. The dog was clipped bald. Scales all over the body. Green pus from the ears.
"My dog had recovered after treatment by a vet," the owner said to me. "But the ear infections and skin disease return again!"
The floppy-eared dog has covered up ear canals. These require weekly cleaning from a young age as there is less drainage and ventilation in covered ear canals. Otherwise, get ear surgery called lateral ear canal resection to open up the side wall of the vertical ear canal.
In this case, for the least cost, I advised ear cleaning weekly and clipping the coat short for the next 12 months.
An English Cocker Spaniel is lovely to look at when well maintained as you can see from this video. But it is a high maintenance dog.
