I was a little concerned when i first got my pup and she got hiccups all the time (i had never had a pup before aside from when i was young) so i asked the vet. he told me that its normal because they arent quite sure how to stop swollowing air yet. it will happen a lot when they get excited or eat or drink.. most anything. nothing to worry about. i had kind of figured that, but i didnt want there to be something wrong with it and it get ignored. hiccups are really cute though... so are her burps. her face is changing and looking more mature, so her cheeks are starting to droop.. when she burps the air goes into her mouth then you see her lips puff out and flop back down and you hear a sound like "whhhhooooooo"
