How is it that dogs have loose bowels after bathing?

Mainly a cold. My dog often does this after taking a bath. If the insulation was done well, this would not happen. But to be honest, it's really a little scary to go to the pet store to bathe the dog. That hair dryer is really loud. If it is blowing people's hair, people will be afraid. It should be nothing. The dog will be fine in a few days. I wish the dog health.
