I was sent this article about the dangers of the Seresto flea and tick collars. I'm not sure if anyone here uses those but I thought I'd post it.

I know Seresto is a popular brand. The pesticides used in it are quite strong and apparently react together to become even more toxic. Guess it all comes down to money and big business as to why this is not widely reported nor recalled by the EPA who has not issued any warnings even though a lot of dogs have become sick or died.
