The link looks suspicious to me.....I'm not going to click on it......

I too wasn't going to click what was linked in the OP so I googled The Dog Allergy Cure: The Natural Way, and it came up with a book listed on Amazon, I'm thinking that's what the OP was referring to. Here's the link to it https://www.amazon.com/Dog-Allergy-Cure-Natural-Scratching-ebook/dp/B009DVHUH8#nav-subnav
