According to multiple sources, dogs tend to hate strong and overpowering scents such as:

• Chili peppers
• Onions
• Ground spices (such as cinnamon, nutmeg, allspice, ginger, cardamom, mustard, and cayenne pepper)
• Garlic
• Citrus fruits (such as oranges, lemons, limes, and grapefruits)
• Vinegar
• Fresh herbs (such as basil, mint, rosemary, and thyme)
• Alcohol
• Household cleaners
• Strong perfumes or colognes
• Mothballs
• Nail polish and remover

It is important to note that while some of these scents may be unpleasant to dogs, they can also be harmful or toxic if ingested or inhaled over a long period of time. Therefore, it is recommended to choose safe scents if using them as a repellent or scent around the house.
