Don’t touch the nose

A dog’s nose is very sensitive and can smell odors that humans cannot smell. There are many olfactory cells on the dog's nose, and their nose is also very fragile. There are no nerve endings and nerve fibers leading to the brain in the dog's nose. So it is very easy to be damaged.

Teeth cannot be touched

Dog’s teeth are extremely sharp, so dogs can crush hard food such as bones. If you touch your dog's teeth with your hands, he may accidentally bite you, so don't make it a habit to touch your dog's teeth.

The tail cannot be touched

A dog’s tail has many terminal nerves, which are very sensitive, and the tail is also a part where they express their emotions. The dog's tail is still used to protect the anus and reproductive organs. These two places are the most vulnerable parts of the dog, so if you touch the dog's tail, its head will convey a message of threat, which is extremely dangerous. They tend to fight back and bite you.
