Hi there, Yes!! This definitely sounds like an elongated soft palate to me! It is characterized by 'gurgly' breathing, and they often sound like they are actually choking on the soft palate. How old is he at the moment?? If he is not going to be neutered soon i would certainly want to look into the soft palate issue a lot sooner, as problems with the upper respiratory system like this, in the long term, can put a lot of pressure on the cardiovascular/respiratory system and cause secondary problems. The surgery for overlong palates is very successful and should make him a lot happier.
Hope this helps
