I know this has nothing to do with drugs but I just want to warn everyone about a bad experience I had last week with my dog ( I know blue will appreciate this) I have two dogs and one is a 10 month old french bulldog . I went to a local big chain pets tore last week to get flea prevention stuff the oil that you put on their back by the neck well he had a horrible reaction to this stuff he was in a trance like behavior he could not lay down kept getting up and going in circles all night had heavy breathing and was like in a world of his own. It totally reminded me of a reaction my son had to drugs awhile ago the dog seemed out of his mind. I gave him two baths to get the oil off of him gave him Benadryl a few times throughout the night and stayed awake to watch him cause he was having labored breathing. He did get better thank god but he now has a terrible burn on his skin and his hair is falling out in the area as well . So please research brands before using any of that stuff on your pets . I wish I had! The next time he gets it I will go back to using frontline even though it is very expensive it is not toxic he has had it before with no bad reaction. If you google flea and tick presentation oils this stuff comes up along with many people's complaints and a class action lawsuit and yet they are still selling this crap at all the big pet chains. So please just be careful . Dee
