It sounds like he is acting fine. There might be something going on but it is not unusual fir puppies to get hiccups. Does he gobble his food or treats quickly? If so, slow down his eating. Being too active can cause hiccups. Try rubbing his tummy, etc.
Banlu-Chi does not eat his food fast at all. What I call hiccups is not really hiccups, but I was try to explain his little body goes up and down like a hiccup. It's almost like tiny little jumps. I'm on a fixed income, and I am scared to take him to the vet becasue they will just run test not really knowing just to make money. He also licks is paws for no reason, I have tried everything like bitter apple but he goes right to his paws and licks. Any thoughts on why he would be doing his licking? Thanks
