If your dog has always been, for lack of better words, a ‘licky dog’ then it may just be a normal behavior for your dog. If it is a new behavior, there can be underlying medical or behavioral issues to address.
If your dog is coughing, has a runny nose, or is slightly off-colour, you may be inclined to think they have a cold. However, the human cold is not contagious to dogs. So the short answer is no, your dog doesn't have a cold.
