Yelling at them
We all know dogs dislike loud noises of any kind – vacuum cleaners, thunder, motorcycles, etc. Yelling will make them anxious or scared, or maybe even completely desensitised to it. Most of the time, they won't even know what you're saying.
Generally, dogs dislike hugs, not being allowed to sniff, a lack of routine, and more. Even the most laid-back dog will hate some of the things we humans do—if they tolerate it, it's just because they love you or don't want to be dominant. Yes, certain things are unavoidable, like vet visits or grooming.

Many (but not all) dogs hate the smell of citrus, so using citrus smells like citronella, lemongrass, lemon, and even bergamot can repel some dogs from an area. You can use these smells in scented candles or sprays to see if it keeps your dog away from an area where you don't want them peeing.
Dogs Don't Reason Like We Do

Obviously, his stronger sense of smell is useful, but it's also because dogs can see movement and light in the dark, and other low-light situations, better than humans.
