i have read all of the stories on here and i am also having a problem with my dog. she’s 7months old now and having extremely bad reactions to SERGEANT’S skip flea and tick shampoo. It has the same chemical that a lot of you have listed in your stories permethrin. I personally think it is wonderful that you have a website such as this, but we need to aim at getting this chemical out of use. This chemical is in other trusted brands too and it is a shame that our loved animals our suffering for this. here are some pictures of our poor Holly and what it has done to her along with her sister that lives with one of our friends.
