Dear Dr. Fox:
Is Frontline safe to use on my two dogs?
I advise using any chemical and pharmaceutical anti-flea and tick products with extreme care and only as a last resort -- as my wife, Deanna, had to do at her animal refuge in the bug-rich Indian jungle. They are a convenient quick fix for ill-informed consumers who risk making their dogs, cats, themselves and other family members extremely ill. People living in semitropical states, where there is more use of insecticides and pesticides, should avoid routine use in their homes and on their pets. Also avoid using any weed and lawn chemicals that can make pets and people sick.
These new-generation anti-flea products are excreted from people's cats and dogs, and are a significant environmental health hazard, along with those poured, sprayed and bathed over the livestock most people eat.
Dear Dr. Fox:
We have a young (17 months) spayed cat. She recently had an adverse reaction to Advantage Multi flea medications. It started with a sore at the point of contact, which she scratched until she had removed the fur. It got infected, and we took her to our vet, who cleaned the area and told us to keep track of it. A few days later, the area looked red, and the cat felt hot, so we took her to an emergency room. She had developed an infection, so they gave her a shot and started her on medication. It seemed to get worse, and a large spot on her back turned black. They excised the area, stitched her up, and we went from there.
