We use touch-me-not (jewelweed, silverleaf) on poison ivy, it stops the itching but only temporarily. You tend to find this plant in low, wet areas or near water. I know the sap can get on something and transfer to something else, so your dogs are probably giving it to you. But I'm doubtful that it would make them itch, with all that fur in the way, although I'm not sure. Hope it helps!

I've read that most dogs are not susceptable to poison ivy, but I'd talk to my vet if she's scratching as much as you say. She could be the exception, or it could be something else, but either way, a lot of scratching is miserable whether you're a person or a dog. Cheryl

My friends dog just got over a bad case of poison ivy. That was the first time I heard of a dog catching it, but it must be possible.
Benadryl, although not a natural remedy, can give you and the dog some relief. I would give the rottie 2 caps of it.
There is a very good ointment at the drug store...sheeze but I can't remember the name. Something like Ivy Dry.
Hope you both heal up soon!

Oh, please don't give your Rottie two Benadryl caps/tabs, you will surely kill her. That is way, way too much, it will shut down her kidneys and/or liver. Based on the breed standard, I am guessing that your Rottie is anywhere between 80-100 lbs, if you want to go the Benadryl route, I would start her off with 1/2 a tab a day for a week and see how that works. Benadryl is made for Humans, trust me, my 250lb husband can be knocked on his behind by just taking one of them, so could you imagine what could happen to your dog? Give her a 1/2 tab in a little bit of Peanut Butter and she will most likely be much better.

I went through this same exact scenario. I took the dogs for a walk and sure enough the next day, one dog is scratching like mad and I have PI. Well I went to the drugstore for myself and took the dog to the Vet. The Vet told me that the dog did not have PI because dogs do not have the same allergic reaction to the oils from PI as Humans do, they carry it on their coat and when the owner pats the nice doggy (or in your case rubs againest a person) that person now has the oil on them and we react to it. What my dog has is season allergies, and since it occurs at the same time as PI, people think dogs have PI. Husband has the same allergies as the dog (it's kind of funny, mind you, not to him but it is to me, LOL), in their case it's ragweed and pine pollen--if one of them is sneezing or scratching I know the other one is going to be soon. In dogs the symptons are scratching, sneezing and licking, especially their pads on their paws. Vet told me to give him 1/3 of a tablet of Benadryl based on his weight (he is about 45 lbs, Dalmation/Beagle mix, not a 'Designer Dog', he is a MUTT), he said to start him off there and see how that is for a week and sure enough three years later it is still working wonders.

As for you, well that is a whole different case. When I take the dogs out for a stroll somewhere where I know there most likely will be PI somewhere, I bring along a bottle of Technu made by a company called Oak'N'Ivy, you will find it almost everywhere, it is made for treatment immediately after contact with PI, it removes the oil that causes the reaction. If you do not get it in time they also make something called Ivy Dry. Good luck!
