Here's why you should seek professional help:
* Yellowish-green mucus can indicate various underlying conditions: It could be a simple issue like allergies or a more serious infection.
* Only a veterinarian can properly diagnose the cause: They will examine your puppy, consider its history, and potentially run tests to determine the reason for the discharge.
* Untreated conditions can worsen: Delaying veterinary care could lead to complications or a more difficult treatment process.
In the meantime, you can:
* Monitor your puppy's behavior: Is it lethargic, sneezing excessively, having difficulty breathing, or experiencing loss of appetite? Any changes should be reported to your vet.
* Keep the puppy comfortable: Provide a clean and comfortable environment.
Remember, your veterinarian is the best resource for your puppy's health. They will provide the appropriate diagnosis and treatment plan.
