Welcome! Thanks for asking your question. My name is***** am a licensed veterinarian and I will be assisting you today. First I need to ask you a few questions so that I can be well informed and give you the best advice.
1- Is he scratching the ear with his legs?
2- How long has this been going on?
Please give me a few minutes to type your answer. Thank you.
Friend, I am sorry that Jack is not feeling well. It sounds like he has an ear infection as you already know. When the ear is very irritated it is best to avoid over the counter ear cleaning solutions. I would recommend for tonight you clean his ear with plain warm water and cotton. Once the ear is cleaned you can apply a small amount of a topical antibiotic like neosporin or bacitracin. Follow up with your veterinarian for a prescription topical medication.
My goal is to provide you with excellent service - I hope I've provided the information you were seeking, if you feel you have received anything less, please reply back as I am happy to address follow-up questions. Kindly rate me when you are done.
