Hi dollface
> Does anyone have any idea's?
In this instance I'd hope the vet would be more pro-active about possible causes if the vomit looks suspiciously like anything other than digested or partly digested kibble and to set your friend's mind at rest there is no possible infection brewing or potential blockage.
That having been addressed and hopefully given the all clear, then it
may be food related - i.e. the puppy possibly being intolerant to one or more ingredients in the diets it's getting. If OK on Origen then I'd immediately switch to that alone - no gradual change over necessary
if intolerance is the likely suspect. If the tummy is upset before the switch then I'd fast pup for up to 12 hours and then reintroduce small regular meals of Origen.
FWIW I think the free-feeding could cause other problems in that since pups are likely to pick up anything and everything no matter how smelly, rank, inappropriate or downright unsafe, then I like to know (a) how much food is going in per meal and (b) if they're chewing when they shouldn't be do I need to hold my nose and retrieve the potential rank thing from it's mouth

HTH, Teri
