How old is your havanese? It sounds like his trachea may be partially collapsing and then he is coughing and gagging to try and get it back to normal. This is common with some smaller breeds and can be very disconcerting. If you can't get advice or help from your vet it may be time to get a new vet. Make sure you take copies of all your records from the old vet if you can though.
