puking dog

I have a mini dachshund that eats so fast that she pukes her food up, then swallows it again. I have tried getting larger kibbel but she still swallows the food. Any advice. Her breath is really bad from her puking twice a day (after each feeding) I dont believe she even chews the food, she swallows it.

Slow her down.
   
Give her one piece of kibble. Wait for her to eat it. Give her the second piece of kibble. Wait for her to eat it.
   
Keep going until her meal is consumed.
   
If she is so greedy she is swallowing the kibble whole, break it up for her so she is forced to eat tiny morsels as if she has chewed it, so you are essentially 'chewing' for her.
   
Do not praise her as she eats. The last thing this dog needs is more encouragement to bolt down food.
   
Wow, I have heard of some greedy dogs but this is an all-time record. This is obviously unhealthy and downright dangerous so hopefully I have said something helpful.
   
Good luck to you.
