Probably sweat. I don't think it would be the urine, she gives the scent off while nursing.

I have never used one, but I know people who do use them and I have heard they do work....maybe not for all dogs, but certainly for some. Some people use a piece of the collar inserted into a 'pocket' on a harness or shirt, and seal the rest back up for later use, and some also use either the collar or a piece of one together with a thundershirt for really stressed dogs/situations. I have also heard of putting the collar into a carry kennel with...not on...the dog...for flying, etc. I have pheromone spray for the cats so I had looked into them after hearing about them, but do not currently have a need for one. I hope it works for yours.

Yes, I think I'd would try that, it worked well with my rescue and make the walks short and sweet. I wonder what freaked her out? Poor little thing.

So from the milk or vulva? And then they take chemicals that act like those chemicals in her milk or discharge and make them in the lab into a liquid that they impregnate the collar for the dog to sniff the aerosolized molecules of the simulated pheromone into its nostrils and then into the bloodstream? Is that something of the process? It is a chemical lab simulation of these chemicals from the mother's milk or discharge or saliva or something? Does a drug lab do this, does anyone know?

Please do update us. I have heard about this but talked to anyone that tried it. We do know Thunder Shirts do work for some and not for others.

Lol, you have more questions than I can answer, I just figured the mother let off a scent when she was nursing and this helped calm puppies. I think most pheromones are hormones and while a gland might produce them, I'm not sure how the odor is presented. Wikipedia gives a basic understanding of them and they have references, maybe one of the references will give you more detailed information. Pheromone - Wikipedia, the free encyclopedia

Thanks, Nancy. I've read about pheromones and know about them. But I was wondering how they make the simulated pheromones that are in use today for dogs. Do large chemical or drug labs make them out of certain unknown chemicals? I think the D.A.P.'s all say they mimic natural pheromones so it sounds like they take chemicals that are manipulated in the lab to act like a natural-occurring product of a dog. That made me wonders who makes them and out of what kinds of chemicals and are there known carcinogens or potential bad things in them like - oh, I don't know what - arsenic or something really bad - even if in small amounts. I don't know if these kinds of things - D.A.P.'s are FDA-approved or go through clinical trials or anything. Something that a dog smells and takes into his bloodstream or nervous system through his nose that calms him and is not actually from another dog or something natural but made as if it's a drug kind of worries me if there's not much info online about its genesis. I can't seem to find a thing about what chemicals are used to mimic the mother's nursing pheromones - so what are they using? Other hormones or what? It's just a general question for anyone that might have any more info.

I think the average person has a skewed view of chemicals. Remember the elements from chemistry class? An element is a substance that is made entirely from one type of atom. There are 117 known elements. This site has a list of all of them. Alphabetical List of Elements So think of the elements as ingredients in a recipe. Every known thing, including humans are made from these elements. Water made in the laboratory or found in a stream is the same, H2O, and the water made in the lab is probably purer. I'm sure that if you do more searching you could find out more about how this is made, but the Internet is still limited as far as a knowledge source, it's better than it was a few years ago, you won't easily find the sort of books you'd find in a university library.

I've never heard of this... Let us know if it works!

Not me. Oh, my, I need chemicals to live - they are usually from the earth - just don't like the harmful ones or even vitamins or good herbs in too large a quantify. I need my good herbs and drugs and whatall. I just hate the ones that contain the really damaging stuff - and when they won't tell or can't tell you what something is made of - I question. For the life of me, I can't find anything out about what DAP's and things like it are made of - specifically, what chemicals(good or bad) are in them! If they are from hormones or what? I've found some manuals with words 30 alpha characters long and such but not very helpful. Was hoping someone on the web had published something for the layperson to read.

That last website is just about pheromones from what I could see and I visited there earlier today in my search. I'm interested in simulated pheromones and what makes up their chemical components - what they contain and their mode of operation within the canine body since they are not actual pheromones. Not much info out there that I can find. Everything says what they supposedly do and where real pheromones come from and all of that but not much on the kind made in the lab.
