HELP! Hypoplastic Trachea with new pup

Hello Bulldog World,

We really need your advice. We live in the Middle East and bought a second bulldog- a beautiful puppy we've called Leo. The day after we brought Leo home, he developed a fever and a cough. The vet told us he has very severe hypoplastic trachea and gave us antibiotics. Leo has been on the meds. for about 10 days and his fever has gone away. However, he still really struggles to breathe. He can barely move, has to keep his nose up, and is constantly coughing and wheezing. I haven't been able to find much reliable info. on the issue. The vet (not a bulldog expert- there are none in the MIddle East that we know of) recommends he perform surgery while another vet suggested euthanasia. The seller has told us to just return the dog and pick another from the litter, but this just doesn't seem right. We are attached to the dog already and are committed to doing everything we can for him. But, we also don't want to see him have to suffer for the rest of his life. Is this something he will eventually outgrow- at least to the point where he can walk and play normally? Which of the aforementioned recommendations should we follow? We don't have a lot of bully resources in the Middle East so thank you so much for your help!
