mysterious occasional diarhea and unrelated vomiting

[MomToAnejo]

Seriously, having a puppy is like having a toddler! Everything goes in the mouth, edible or not! Anejo is a 10mos old tweeny doxie, and gets occasional vomiting and diarhea. The vomit is yellow, foamy and VERY smelly, but no grass particles in it. Usually the diarhea lasts for half a day then back to normal. This time it's lasted two days. He eats grass almost every time he goes out, and only sometimes will eat his own poop. I've taken a fecal sample for testing for parasites because the vet said any diarhea in puppies is bad...still waiting for the results. Any ideas? His energy level is normal, he is eating and drinking normally. He has NOT eaten anything strange from the yard (I watch him), nor had any human food that would cause this. The vomiting and diarhea do not happen at the same time.

Hi and welcome to the board
When he vomits, do you notice it happening at any particular time? Any sort of pattern? What do you feed him, and how often?

No mystery at all, he's been diagnosed with giardia and is now on medication...he's doing well
