Puppies get hiccups all the time! No suggestions on how to get rid of them... maybe encourage drinking some water? The good news is that they do grow out of it! But don't be alarmed... its totally normal.
This is my first time using this forum. We have a 3 month old chocolate/cafe labradoodle, Noelani. She has had hiccups more times than I can count. We got her at 8 weeks, she had the hiccups almost all the way home (about 3 hours). I asked the vet about it. He said that it occures because the nerve that goes to the diaphrgam develops faster than the diaphragm. He said Lani would grow out if it, but didn't say when. Hope this helps.
