Cody is 4months old and he still seems to get the hiccups.. So not sure when hiccups go away.. But I know its very normal, His are mostly right after he eats and sometimes drinks..I think that maybe he eats or drinks too fast ?? not even sure if thats the cause. but don't worry.. Since your pup is only 9 weeks old, Guess your new to BW so.. Welcome to Boxer World and the wonderful and sometimes crazy yet always full of love lovicon of owning a boxer. You'll find this is a great site full of lots of helpful information and wonderful caring boxer owners who love their wonderful, silly loyal friends, and we're all pretty partial on here and love the Breed .. Guess thats why it is called Boxer World :O) Enjoy the site its awesome.. And you'll be hooked in no time..
