Hopefully you can convince your vet to prescribe cream, medication, or shampoo before the test results come back from the lab.


A daily dose of medication will most likely be recommended for your dog and you should follow the instructions. Creams are not as effective because your dog can simply lick the cream off or can rub it off. Anti-fungal shampoos work well since you treat your dog without the dog being able to disrupt the treatment. You will most likely need multiple shampoo treatments.
