It’s okay to bathe your dog if he has a cold. It’s not too late to wash your dog after he has recovered from the cold.

Can dogs take a bath if they have a cold?

Do not take a bath if a dog has a cold. It is best to wait until the dog has recovered from the cold before bathing the dog. The dog may catch a cold because it catches a cold. Bathing the dog at this time may aggravate the dog's cold. Pay attention to the water temperature when bathing your dog. Water temperature that is too low can easily cause your dog to get sick. After bathing the dog, dry it in time and do not let the dog dry naturally. This will make the dog catch a cold easily.
