I got this response to my first blog post/call for help from Riyo and Darcy’s first mom 🙂 I will go look for this stuff and try it out! Also was told by another Papillon expert to try something called Comfortis.:

Use a yard and house spray with IGR in it. Will be more expensive, but has a chemical in it that basically neuters fleas. Most sprays etc…only kill the adult fleas leaving the eggs, and other stages to hatch out and form into adults only to carry on the problem. IGR is an insect growth regulator that neuters them when they come into contact with it so the ones that continue to hatch out even after spraying will not be able to reproduce thus putting a kink in their life cycle. It may not totally stop the problem, but the IGR usually lasts for a while. Also, spray in the evening time near as sunset as possible. Sunlight breaks down the poisons and makes it not last as long and be less effective. Giving all night to begin killing is best. You should also repeat the treatment in 7 days with most sprays.

Yes, fleas are showing signs of getting immune to things that have been on the market for a while. That’s why we are always waiting for the next big break through product. Treating the dogs and the yard is the best you can do. Just be sure to be careful when looking into those newer products that claim to do multiple things all in one such as fleas, worms etc…They are often too harsh for toy dogs and cause an array of reactions from neurological to even death in some cases. I have also stuck with Advantage more than frontline as I know more dogs that have had issues with frontline from irritated skin to coat loss.
