Smells that dog’s hate!

Dogs are olfactory animals. A canine sense of smell differs to a great extent from us. It is almost forty times stronger than humans.

So, dogs are no different from a variety of flavors when finalizing the flavors that are not good for us and what fragrance is good for us.

Yet, for dogs, these types of smells feed them with information that helps them decide their next course of action.

On a happy note, this canine aversion to specific odors protects anything you do not want it to damage.

Make notes of all the smells dogs hate and use this information to protect your dog and your home.

Dogs Sense Of Smell

What makes this small piece of machinery work?

Putting it in simple words, dogs can detect some smells in parts per trillion. It means that a dog could find a small teaspoon of salt dissolved in a large reservoir filled with water.

An Amazing Nose for Odors

What we do not have, but the dogs have? They have something close to 300 million scent receptors, compared to just six million in humans.

A Presence of Second Olfactory System

Dogs have a second olfactory network. It is called Jacobson’s organs or the vomeronasal organ. This organ picks up pheromones, a significant set of chemicals that display mating readiness.

It is as if this organ functions with its separate library of scents.

Do you know? Your dog nose is almost tens of hundreds of times as efficient to smells as yours.
Do you Know? In reality, humans cannot wiggle their nostrils separately. Only dogs can.

10 Smells That Dogs Hate

1. Rubbing Alcohol (Isopropyl)




Some people seem to dislike or like the strong odor of alcohol to rub. You are not alone in this issue. Canines are haters when it comes to rubbing alcohol.

If you feel your dog does not behave properly, do not spray or pour the rubbing alcohol, but take a few cotton balls.

For added security, ensure that soaked cotton balls are safe from children.

That is one of the reasons dog owners use water instead of alcohol to clean their pet injuries.

It is essential to contact a vet to clean the wound.

Some other products that canines hate are antibacterial gels and alcoholic beverages. Alcoholic drinks are also toxic to pets.

2. Citrus




Humans, in general, love the rich smell of citrus. These fruits not only remind us of the long summer ahead, but the aroma is also powerful. All canines hate the smell of this fruit, be it grapefruit, limes, lemons, or oranges.

The dog’s sense of smell is forty times stronger than humans. If the perfume is hard for us, imagine how hard this will be for dogs. It can affect the respiratory tract to an extent.

They dislike smells produced by essential oils that carry this aroma. Essential oils emit a much powerful fragrance compared to the actual citrus fruit itself.

If you wish to use citrus, remove the peel, and place it in specific areas. You can fill a bottle with lemon juice and spray it on areas you want your dog to avoid.

The essential purpose is to stop your dog from dirtying that particular space and not make him sick.

5. Vinegar




Vinegar is another item used as a dog repellant. Dogs have sensitive noses. They love to turn away their face with the very thought of vinegar.

As with other citrus fruits, the smell of vinegar is powerful and unbearable to dogs. Apple cider vinegar is good for dogs if used in moderation.

You should know how to apply apple cider vinegar so that your dog remains safe and secure.

Apple cider vinegar prevents all the bad smells. We recommend you mix this with their regular shampoo to reduce its intensity.

Never apply this solution directly to their heads, and remember to rinse the area after the application. Another way is to soak wet cotton balls in vinegar and place them in strategic zones.

As vinegar is not to be used directly on plants or the ground, you can try the cotton ball. 

6. Chili Pepper




Chili contains capsaicin, the compound that irritates a dog’s nose. Due to this, most canines will avoid items that smell like chili.

You can sprinkle or rub the cayenne powder on areas or objects where dogs are restricted.

If necessary, you can mix chili pepper with water and prepare a spray solution.

Chili peppers are not poisonous to dogs, but it can severely irritate the throat, nose, and eyes.

Touching the chili pepper with your bare hands and rubbing it on your eyes leads to a burning feeling.
