Is a yellow runny nose a cold in a dog?

The first thing to do if you have a yellow nose is to check for distemper. If there is no distemper, blood tests should be done to determine the level of inflammation and a radiograph should be taken to check for lung infection. Depending on the results of the tests and the condition, an appropriate treatment plan should be chosen. If nasal discharge is heavy and interferes with breathing, nebulisation may be required and if the dog is not eating, fluids may be required. Puppies have poor body resistance and are unlikely to heal on their own, so it is important to seek medical attention in a timely manner and to strengthen your dog’s nutrition and resistance during treatment
