Do Dogs Hate the Smell of Bleach? The Surprising Truth

September 20, 2025 |

Regardless of working in a vet setting, doggie day care or as a groomer, using bleach might be part of your tool kit in your cleaning routine. It’s been around forever and bleach can kill bacteria and viruses and remove mold from various surfaces.

Sure, bleach is an effective cleaning agent, but did you know that bleach can harm dogs through their nose?

Because of their heightened sense of smell, dogs are easily attracted to the strong odor produced by bleach. Inhaling an excessive amount of bleach can cause several side effects for dogs, namely kidney damage, aspiration pneumonia, and blood serum changes. Bleach poisoning through inhalation can also damage a dog’s gastrointestinal tract. Who knew?

How can you possibly clean kennels or perform proper veterinary sanitization without compromising a dog’s health? By simply using the right pet cleaning products designed specifically for animal care, especially ones from Alpha Pet Tech.

Contrary to what you might expect, most dogs are actually attracted to the smell of bleach rather than repelled by it. According to the information from TheHaloPets, many dogs and cats are drawn to bleach scents, though the strong fumes can be toxic to pets.

The article specifically mentions bleach in the “What Smells are Toxic to Dogs?” section rather than in the list of scents dogs hate. It states “Many dogs and cats are attracted to the scent of bleach. However, its strong fumes could kill our pet animals.”

This is important information for pet owners who might assume bleach would work as a dog repellent. Not only will it likely not keep dogs away, but it could potentially harm them due to the toxic nature of bleach fumes, with younger pets being especially vulnerable.

If you’re looking for effective scents to repel dogs the article suggests citronella and citrus fruits (like lemons, limes, and oranges) are among the most effective options. Other smells dogs typically dislike include

  1. Spicy peppers
  2. Alcohol
  3. Vinegar
  4. Ammonia (though some dogs are attracted to it)
  5. Mothballs
  6. Menthol
  7. Eucalyptus
  8. Coffee grounds
  9. Coleus canina (the “Scaredy Cat” plant)
  10. Nail polish remover
  11. Strong scented candles
  12. Peppermint oil
  13. Air freshener sprays

For safer alternatives to keep dogs away from certain areas, consider using citrus-based sprays, vinegar solutions, or planting dog-repelling plants like lemongrass or citronella.
