Since our dog was badly attacked a few months ago we have been investigating many many different techniques and products to help stop attacks in progress (on top of preventative measures) and one I recently stumbled upon was a product called Sentry Stop That!.

It states that it has a Lavender chamomile fragrance as well as pheromones (I have been told it contains 0.1% Pheromone); but the main point of it is it's "hissing sound" it makes.

The product can be found here: https://www.sentrypetcare.com/products/sentry-stop-that-noise-and-pheromone-spray/

Based on info found in @elmy's answer it appears this spray uses Pig Pheromones; what type of pig pheromone it uses is unclear however.

To get the to the root of my question, when our dog was attacked, she was attacked by another dog that was on heat (or just coming off heat); so my question is, would a product that contains Pheromones make dogs that are on heat/coming off heat more horny/wild - because obviously that is the opposite of what we want.

I guess because it is a pig pheromone it shouldn't be an issue as it comes from a different species, but something that stood out to me from the article was this part:

Having shown its effectiveness, McGlone was able to classify androstenone not only as a pheromone but also as an intermone, a term developed by him and his team that refers to a product that is a "pheromone in one species and has a behavioral effect in another species, but we do not know if it is a pheromone (naturally produced) in the other species."

I have asked the supplier but it seems they didn't really want to directly answer the question.


1 Answer 1


Short answer

This product is intended to stop over-excited behavior in dogs like barking and jumping. I couldn't find any information if it could stop a dog fight. It seems to have an immediate effect, but I couldn't find any information about it being used on an attacking dog.

Long answer

Please ignore my rant. The information provided by the manufacturer is zero. Null. Nothing. You even have to create an account just to able to view the Material Safety Data Sheet. There is no list of ingredients or any other technical information. They claim that it's "Clinically shown to provide quick, effective results without causing harm to pets" without even a hint of proof. This kind of marketing would be absolutely illegal in the EU and I cannot fathom how or why this is still possible in the US. end of rant

By pure chance I stumbled over this article which explains how this product was invented:

Then again, McGlone is not like most dog owners in that he is a professor at Texas Tech University who just happens to specialize in animal welfare and behavior. And, in that capacity, he just happened to have a product on hand at his house from a previous research study called Boar Mate, an odorous concoction which helps farmers with swine breeding.

So, he gave one little spritz to his dog, Toto, and immediately the dog stopped barking. Right on the spot.


McGlone said Boar Mate contains a pig pheromone [...]. In this case, the pheromone produced is androstenone, which, when secreted by male pigs, is picked up by female pigs in heat and ready to breed. It is a foul-smelling odor for humans and also affects dogs through their olfactory system.


Having shown its effectiveness in curtailing bad behavior, the product was developed and hit the stores as Stop That for both dogs and cats [...]. But, McGlone warns, it's not an end-all, beat-all to stopping dogs from barking, as the effects last just about a minute.

The "scientific research" they conducted had a sample size of 100 dogs, which is not representative at all. They have no clue why and how this pheromone affects dogs and what possible long term effects it could cause.

Furthermore, McGlone and many product reviews state that after just 1 - 2 days of "training" the dog will immediately stop the bad behavior after being shown the can. This makes me suspect (without having any means to confirm or refute) that the effect of the pheromone is extremely unpleasant for the dog, but without causing pain or any other feeling they can vocalize or express in body language. Maybe it's like a really bad dope for dogs. Who knows? The manufacturer sure doesn't...

This is the equivalent to saying "I only hit my dog with a stick for 2 days and now he stops barking and cowers whenever he sees a stick. I'll market my stick as a magical dog trainer." This product feels as bad to a dog as being hit with a stick, but since we humans see only a harmless spray can instead of a stick, we ignore the rather blatant signs of discomfort.

The only positive aspect I could see is that it's effect sets on immediately. If it could deter a dog fight (which is not proven) it would probably work quick enough to prevent further injuries.

  • Thanks a lot Elmy - that Science Daily article was an interesting read, and finding out they use Pig Pheromones. But yes, I actually got them to send the Material Safety Data Sheet to me when I requested it by email, but they wouldn't tell me the ingredients as it was a "secret", other than to say it contained 0.1% Pheromone. With regards to dog attacks, from the Amazon reviews I have read, it's much like other products, many say it works, then you get a few that say it doesn't - but that seems to be the case with everything, there is no fool proof method to stop dog attacks in progress.

  • I was trying to decide between this and "The Pet Correcter" - this one sounds like it's the same as TPC with an additional mist, so thought it may be more effective - according to the small study, it was.

  • One bit that stood out in the article though, where you say beings are generally only attracted to pheromones from the same species... "Having shown its effectiveness, McGlone was able to classify androstenone not only as a pheromone but also as an intermone, a term developed by him and his team that refers to a product that is a "pheromone in one species and has a behavioral effect in another species, but we do not know if it is a pheromone (naturally produced) in the other species."" - was just something that stood out to me.

  • @Brett Yes, exactly that paragraph got my intetest as well. They could have coined a new term that'll start a whole new branch of scientific research, or they could have missinterpreted the reaction and will be refuted later. We will see. Anyways, I'm still extremely sceptical of the product. Something that seems too good to be true often isn't true in the end.

  • Thanks Elmy. Your answer contains some excellent information, but I'm going to wait to see if any other answers come with additional information before accepting one - I actually updated my question to note the information you found. As s side note, it appears Pigs excrete 4 different types of Pheromones.
