Hi I have a small breed litter of puppies all doing well there is one smaller puppy they are six weeks old the smaller puppy eats her food but seems to regurgitate her food after every meal although she's small she's still behaving like any other puppy should she does not behave like she's I'll or in pain after the regurgitation she just eats it back up then it stays down anyone had any experience on this happening and do they grow out of it any help thanks

I've had the occasional adult do this, especially if they eat up too fast (it bounces) but not in a puppy this young.  I think I'd have the vet take a look.
