Here's why:
* Cold sores in puppies are not a common occurrence. They are usually caused by a virus called Herpes Simplex Virus (HSV), which is typically associated with humans.
* Symptoms can vary and may resemble other conditions. It's crucial for a vet to properly diagnose the cause of your puppy's symptoms.
* Treatment options are specific to the underlying cause. A veterinarian will determine the best course of action, which might include antiviral medication, supportive care, or other therapies.
Please remember: Self-treating your puppy can be dangerous and could worsen their condition. Always rely on your veterinarian for accurate diagnosis and treatment.
