Did it happen when Canidae changed their formula?
Advantage Multi is full of pesticides and insecticides.
It is anything but gentle...
It is also pretty new (the multi part) and I wouldn't be comfortable using it until more data is available. I personally also don't like over the shoulders treatment for heartworm.
How about going to Interceptor and maybe Frontline if you need something for fleas?
