Nausea when smelling dogs can be caused by a variety of factors. Some people may be allergic to dogs, and the dander or saliva on a dog's fur can trigger allergic reactions, including nausea. Additionally, some people may be sensitive to the smell of a dog's natural body odor or the scent of their fur, which can lead to feelings of nausea. It's also possible that the nausea is not directly related to the smell of the dog, but rather to other factors in the environment, such as anxiety or stress related to being around dogs. **

It is important to address the underlying cause of the odor to effectively manage and reduce it. **

One can scratch without smelling by simply not bringing their nose close to the area being scratched. Smelling is a sense that requires the odor molecules to reach the olfactory receptors in the nose, so as long as the nose is not close to the area being scratched, there should be no smell involved. Additionally, if the scratch is on a part of the body that does not produce a strong odor, such as the arm or leg, then there may be no noticeable smell associated with the scratching. **
