Hi there, my name is ***** ***** I am a registered veterinarian and I would like to try to help you.
I am sorry to hear about your dog.
The fact that he is crying when you try to touch the ear would certainly be a strong indicator that something is wrong. The treatment he has received would certainly clear most infections up. There is however a possibility that the infection has come back. I would certainly recommend having him checked again as he may need further treatment. When ear infections are recurrent it is usually a good idea to get a swab of the ear that your vet can send away and grow the bacteria (or yeasts) and test which antibiotics are best at killing them. This way you can target your treatment to any bugs that are left over from the last treatment and see what is likely causing the issue.
No problem, I hope this is helpful? Is there anything else I can help you with today>
I can see you have gone offline, just let me know if there is anything else you needed to ask or I can help you with today. If you are done please don't forget to rate me. All the best with Ben, Sophie
