Please be strong, disciplined, and quick to act. Your dog's life right now depends heavily on you.
Apply the following protocols under strict veterinary supervision, with regular monitoring of liver, kidney, and hematological function. Treatments must be adjusted according to the patient's condition and response.
Let's start with the fundamentals
AVOID all of this
Avoid vaccinating, bathing, or exposing your dog to stress, travel, confinement, loneliness, dirty places, or places that are too hot or too cold.
According to one of the studies included in this guide, you should avoid these medications because they could open the blood-brain barrier that protects the dog's brain:
NSAIDs : Acetylsalicylic acid, Paracetamol/Acetaminophen, Ibuprofen, Ketorolac, Metamizole, Naproxen, Diclofenac, Carprofen, etc.
Corticosteroids : Dexamethasone, Triamcinolone, Prednisolone, Prednisone, etc.
Others : Ivermectin, Avermectins, Ranitidine, Enrofloxacin (although another study allows the use of this medication, use at your discretion), Ciprofloxacin, Azithromycin, Cephalexin, Erythromycin, Spot-on pipettes (e.g., fipronil, imidacloprid, selamectin), Eye drops/ear drops with decongestants (e.g., naphazoline, phenylephrine).
About baths: regular baths are not allowed. Only medicated baths are, such as the colloidal oatmeal or cortisone baths in section 4 (Skin Infections).
Medications the sources disagree on: Dr. Sergio De La Torre recommends avoiding Azithromycin and Enrofloxacin, but the American/Austin Pets Alive (APA) protocol uses them for respiratory symptoms (section 1). The same goes for corticosteroids: section 4 uses cortisone in baths and in a skin cream. In these cases, whether to use them is up to you and the veterinarian who is caring for your dog.
MAKE SURE to do all of this
Be patient with your dog, because he's the one facing the disease.
Apply all treatments with veterinary assistance and consider adjusting certain parameters if your dog has any pre-existing condition.
If you can't monitor with specialized tests continuously, at least do it at the start, and every time you can afterward.
Be responsible and disciplined with the timing of each medication, and always ask if you think something might be wrong, for example the dose. Remember that many human and animal patients die from wrong doses or wrong diagnoses.
Keep the area where your dog lives clean and disinfected, but don't expose him to breathing in the cleaning products themselves.
If you don't want to spend excessively without needing to, try to buy generic medications whenever you can.
