It is crucial to consult a veterinarian for any health concerns your dog may have.
Here's why:
* Diagnosis: Only a vet can accurately diagnose Malassezia and rule out other possible causes for your dog's symptoms.
* Treatment: The appropriate treatment for Malassezia can vary depending on the severity of the infection and your dog's individual health. A vet can prescribe the safest and most effective medication, which may or may not include Bactrim.
* Safety: Bactrim (sulfamethoxazole and trimethoprim) is a powerful antibiotic that can have side effects, and it's not suitable for all dogs. Your vet can assess if Bactrim is safe for your dog based on their medical history, age, and other factors.
Please schedule an appointment with your veterinarian immediately to discuss your German Shepherd's condition and receive proper medical care.
