Oops about the Telfast. 
We got rid of the grass in the backyard, so could just be airborne allergens. 
Just checked the box again and yeah, says 180mg (http://tinyurl.com/3y3l847). 
We started the Malaseb as was advised by the vet initially. 
Bella weighs approx 20kg. 
We've spent a lot of money on trips to the vet with no real outcome.  Like I said, cortisone works but trying to avoid it due to it shortening her life span.
