OH! Speaking of dogs... ALL of my poison ivy rashes come from my cats!!! They walk through the stuff and get the oil on their fur, I pick 'em up and hold them and then a couple of hours later, I start to itch. I've begun to recognize it and if I catch it soon enough, the jewelweed soap that I have will wash off the oil and the rash goes away. But since I am VERY allergic, if I ignore the itch, it will spread and I am in misery and I have to get a course of prenisone to clear up the rash.
