You can't. Because toilet water contains alcohol, dogs have a keen sense of smell and sneeze when they smell it. After a long time, the dog's nose is immune to these smells, indicating that the dog's nose has been partially damaged.

In this way, the dog's nose will become very dull, affecting the dog's actions and mood. There is no special structure in the dog's nose that leads to nerve endings and nerve fibers in the brain, and it is extremely vulnerable.

Extended data

The smell of toilet water is a bitter blow to the dog's sensitive nose. Dogs' olfactory nerves are densely covered on the nasal mucosa, occupying four times the area of human beings. The average human has only 5 million olfactory cells, while the dog has 220 million. Dogs are more than 40 times more sensitive to smells than humans.

When you spray toilet water, you must take care of your dog's sense of smell. You must never spray your own perfume on your dog. If you want to spray perfume on your dog, you can choose pet perfume, which is specially designed for dogs. There are many kinds to choose from.
