Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
Hello, I am Dr Ola B.. This site is meant specifically for licensed veterinarians to give you medical advice and point you in the right direction for your pet. Unfortunately, it is unlawful for a veterinarian to provide a medical script without a "patient-client" relationship; meaning they have seen, examined the pet and done proper diagnoses to warrant that any medication is needed. It is possible that the skin issues your dog is having currently is called by a different organism than previous skin condition; thereby warranting a different medication. I would recommend an appointment with correct diagnostics tests (including skin cytology to rule out bacterial presents and/or yeast present, skin scrape to rule out presence of Demodectic or Sarcoptic mange and Wood's Lamp/DTM culture to rule out ringworm) and a thorough physical examination to rule out other medical conditions that may be contributing to the skin problem.
If your dog has been previously prescribed this medication in the past, you may try to contact that particular veterinarian to provide you with a refill prescription. However, it is likely that he/she will want to re-examine you pet and follow the correct protocol for dispensing and/or prescribing medications.
