What Smells Do Dogs Hate?

What Smells Do Dogs Hate?

It may seem like dogs love just about everything with a scent—they certainly have a fondness for some scents we humans can’t stand—but there are actually many smells humans love that dogs hate, and these scents are the perfect way to keep your dog away from your most valuable and fragile possessions(or, really, anything you don’t want your dog chowing down on).

Here are some of the most common scents dogs hate:

  1. Citrus

We humans love citrus fruits and citrus smells, but dogs find them incredibly unpleasant. There are thousands of lemon scented products you can use to keep your dog away from precious belongings, but you can also use any other citrus scent you can get your hands on.

  1. Vinegar

Vinegar is one of the most useful substances around. It tastes great mixed into a whole variety of things and it’s also one of the best natural cleaners for, well, pretty much every surface in your home. And there are many different types of vinegar which are ideal for different things, ranging from standard white vinegar to apple cider vinegar to the balsamic vinegar in your salad dressing.

To dogs, however, every single type of vinegar smells and tastes disgusting. If you want to keep your dog away from surfaces in your kitchen or dining room, cleaning them regularly with vinegar is an excellent solution.

  1. Chili Peppers

Chilies actually cause your dog mild irritation in the nose and eyes when sniffed, which means they make extremely effective dog repellants but you might not actually want to use them. If you do, remove the seeds and the white veins inside the peppers, which contain the highest concentration of capsaicin, an oil that tricks the brain into feeling pain(it also creates most of the heat in chilies).

There are a large variety of chilies you can use for this purpose including Jalapeño Chiles, Fresno Chiles, Serrano Chilies, Bird’s Eye Chilies, Habanero Chilies, Poblano Chilies, and New Mexico or Anaheim Chiles.

  1. Ammonia

Dogs also hate the scent of ammonia, which is a chemical used in many cleaning products. This chemical can actually cause serious irritation and must be used carefully if you choose to use it at all.

A note about perfume

You may love your perfume or cologne, but chances are your dog hates it. Dogs have more than 220 million olfactory receptors in their noses, so a perfume that smells mild to you is incredibly strong to them. Even your scented deodorant smells highly potent to a dog, which is why many veterinarians have scent-free policies.

Many perfumes also use isopropyl alcohol, which is highly toxic to dogs. Even breathing in the vapors from isopropyl alcohol can cause serious nervous system disorders, nausea and vomiting. This means that perfumes aren’t even good dog repellent.

Giving up perfume to make your dog more comfortable may seem extreme, but it will make a world of difference to your furry friend—and if you really can’t do it, opt to use less instead.

Final advice

How sensitive your dog is to a specific scent depends largely on their breed and partially on their individual personality. You may find that your dog isn’t particularly repulsed by citrus, for example, but that they won’t even go into a room where you’ve used vinegar. Test out different scents in various parts of your home to figure out what makes the best repellent for your dog.
