4 Mth female dane pup/ throwing up

Question
My 4 mth Dane pup (grayce) is seemingly healthy and very happy.  Recently she started throwing up after eating.  She started doing it a few hrs after eating and now immediately.  The food doesn't even digest.  Her belly is not bloated, she is not foaming or having trouble breathing.  She is happy and acting normal except for the vomiting.  I have not changed food brands; we used to feed her once daily and now have tried to split it up to 2-3 times daily thinking its too much at once.  She does eat super fast.  Do you have any ideas on what might be wrong or any suggestions.  I'm starting to get worried!

Answer
If she is eating fast then you need to slow down her eating pattern...first of all, if she is still on puppy food, you need to put her on a large breed adult food. Preferably something with less then 24 protein and something that does not have by-products and corn as the main ingredients.

Second a four month old puppy should be eating 3-4 times a day and should NEVER eat once a day. It should be spread into 2 equally proportioned meals, when she is older.  

To slow down her eating what you need to do is either 1)hand feed her the food 2)buy her a slow down bowl 3)put a huge rock into her food bowl and put food around it, make sure the rock is clean of course and big enough so that she does not try to eat that. 3)Also, you can try to soak the food a little so that it becomes moist.

Do not let her out to run and play for at least an hour after eating as this can cause bloat, even in puppies. This also applies for water.

If the throwing up continues as always consult your veterinarian as there may be some sort of underlying problem that I would not be able to determine.

Another possibility is that she ingested something like a sock or underwear and this has blocked her intestines, which is why she is unable to keep food down, this will require a veterinary visit and they will do an x-ray to see if there is anything obstructing her digestion tract.
