what was she doing! so worried!

last night chiwi scared the crap out of me! we were laying in bed, she had her pig ear and was munching on it, i was petting her and watching tv then she stands up and i say chiwi it's sleep time lay down but she hopped out of her bed and was looking at me so i said you gotta go potty so i put her down and she walked away from the wee wee pad and got a drink. then she went pee and started doing this weird breathing thing, almost like she had the hiccups and was gasping for air! i picked her up and opened her mouth thinking maybe some pig ear was stuck in her throat but i couldn't see anything. she did this for like 15 minutes. her gums never turned a different color they stayed pink , she never sounded like she was wretching and never looked uncomfortable (i thought oh my baby is bloating because she ate her dry food for the first time last night about 20 minutes before this started happeneing and she ate a big amount, like 1/4 cup maybe less it wasn't measured out.) but when i thought of the signs of bloat it eased my mind. her belly felt real full and round but i think just cause she was full from eating like she did. then out of nowhere it stopped. she was fine. we went bck upstairs and i tried to hold her for awhile but she hopped into her bed to go to sleep. well i stayed up for about 4 hours checking on her making sure she was breathing and stuff. i was so scared! i had no clue what was going on. i still don't. my mom said maybe it was just hiccups, i thought maybe a small piece of pig ear not big enough to block the airway got stuck but she worked it out, what about that collapsing trachea what's the signs with that? she's been sleeping a lot today and wasn't very hungry this morning, only ate a bite or 2 of food but maybe she is still full from all that she ate last night? i'm still nervous and i am probably going to call work and talk to one of the vet's there. but i was wondering what you all thought of this.
