I am not experienced enough with the AKC paperwork, but others her are and will be along to provide some insight.
Unfortunately, the palate is a known issue with the breed and in most cases a vet will wait to do the surgery till the pup is 2 years old because they continue to grow and you do not want to have to do the procedure again. When we got Cheli, we were told at the time, he would need the procedure and our vet straight up said, he will struggle and rattle we breathing, when did the procedure in May of this year... he is much better, but not perfect.
