8 Common scents what your dog hates:

1. Citrus

This type of scent is very much refreshing for humans, which is why it is often used in cleaning agents at home, air fresheners for cars and essential oils for diffusers.

The main reason why the scent of citrus is very common in every household is because this type of aroma is usually strong, which indicates that the smell will last long.

This aroma may be appealing for humans, but it is very much the opposite when it comes to dogs. As previously mentioned, citrus gives off a very strong smell, and since dogs have a way more sensitive sense of smell than humans, a pungent aroma such as citrus might cause irritation in the dog’s respiratory system.

2. Vinegar

Typically used in cooking, vinegar has an aroma that is not pleasant even for humans. Because of its strong acidic smell, dogs dislike it as well.

However, vinegar can also be useful for dogs in some way. Most dog owners place vinegar around the house that they don’t want their dogs to access. This helps prevent dogs from urinating in those places. In addition to that, apple cider vinegar is used as a substitute shampoo for dogs.

Apple cider vinegar will help in reducing that musky smell that dogs normally have, but since apple cider is twice as pungent as a normal vinegar, it is better to mix it with normal dog shampoo and to rinse well.

3. Chili

Food spices such as chili tend to give off a very strong aroma that easily wards off dogs. Because of the strong smell that this spice emits, has any direct contact between chili and your dog can cause immediate respiratory issues or excessive sneezing for your furry pal.

4. Alcohol

Often used for disinfecting wounds, the aroma that alcohol gives off will depend on its content. Regardless of how strong or how weak the smell of a certain type of alcohol is, that aroma will still be hated by dogs.

If your dogs get wounded or injured, it is not advisable to use alcohol as a disinfectant, because once the pet has a close encounter with it, the smell of the alcohol can become an additional source of major stress and make the pain experienced because of the wound even worse. It is better to use water to clear off the wound first and then pay a visit to the vet for proper treatment.

5. Nail polish

A cosmetic product that women normally use to paint their nails, nail polish is made up of different chemical compounds which include formaldehyde and Isopropyl alcohol. These chemicals give off a strong smell that even other humans can’t stand. 

Due to the number of chemicals that the substances contain, the smell that they give off also has a chemical nature, which pretty much repels dogs. When using cosmetic products with high chemical contents, it’s better to look for something that is odourless or better yet keep these products away from your dogs to avoid serious damage to their respiratory system.

6. Cleaning products

Most products used in cleaning houses contain chlorine and ammonia. Almost all of those products contain a lot more chemicals that are not only harmful to humans, but are also very much dangerous to dogs.

Close contact with these types of products can damage your dog’s oesophagus directly, which can eventually turn into extreme harm for the respiratory system and possibly pose a threat to your dog’s life if not treated properly.

It is highly advised to keep your dog outside the premises during cleaning day, to avoid any accidents with the cleaning products used and to prevent dogs from inhaling the dust during the cleaning process.

7. Perfume

In order for perfumes to have a long-lasting fragrance, their smell is usually strong. Other perfumes also contain chemicals that may not affect humans, but can cause great damage to dogs due to their sensitive sense of smell.

Other than the pungent smell caused by perfumes, dogs also differentiate and recognize humans based on their distinct smell; and when it’s layered over by perfume, your dog can become very much confused, as it may not recognize your natural aroma.

8. Mothballs

As the name suggests, mothballs are used to keep moths away, but they are also an uncommon tool used to repel dogs. However, it is not advisable to use mothballs, since they contain numerous chemicals, some of them being even poisonous; this makes them potentially deadly for both dogs and humans.

The use of mothballs is very much discouraged especially when there are puppies around. Their sense of smell is not as developed as that of adult dogs, and since mothballs are new to them, they may have the tendency consume them the same way they tend to consume anything that crosses their path. If eaten, mothballs can cause instant death, though.

Conclusion

A dog’s sense of smell has different types of uses that also benefit humans in a lot of ways. Not only can dogs sense danger, they can also track down missing people or even detect the presence of explosives in a particular area.

Humans need to pay attention to their dogs’ high sensitivity in smell, because a lot of products that pet owners use in their daily lives can cause serious damage to a dog’s respiratory system. Dog owners should do their fair share of research in order to find out what needs to be avoided and what is safe around dogs.
