I bite.
Collies and other herders are sensitive to ivermectin due to a gene mutation, allowing the insecticide to cross into the central nervous system...do you know what product/treatment set her off, Ann? It may have been the gene mutation that caused the flare up, but usually only high doses of it cause problems. I'm curious )
Diatomaceous earth is a good alternative should you need it and as long as you take the precautions when using it. I always thought it was cool- it is actually the remains of diatoms - microscopic underwater plants/creatures and algae. Under the microscope it looks like a kaleidoscope with different shapes. The particles are like little shards of glass that essentially cut the insect and dry out it's waxy protective coating. It should not be inhaled and is also very drying, so you'll want to use a mask and gloves. It is very drying to the animal's skin, and an eye/respiratory irritant, so something else to keep in mind. If the animal isn't sensitive to the flea treatments I would use it and perhaps use the diatomaceous earth for yard treatment. If you do decide to try diatomaecous earth, make sure you get the food grade.
