I have found some very good info on line. One site that I refer to all the time is the one that Terri Shumski answered the questions. Am I allowed to put the addy on this forum? There are many breeder web sites that include the info. Or, vet sites. The explanation of the collapsing trachea is not simple but it is not something that occurs due to crowding in the womb. The cartilage rings that hold traches open should be ROUND and firm. In a collapsing trachea, the rings are more oval and too FLEXIBLE allowing the surfaces of the trachea to stick together and collapse, especially with exertion.
There is a new surgical procedure being tried at the PA vet school but I don't know if it is available to the general public or still in the testing phase. |
