Chihuahua Vomit

I have a 1 year old Chihuahua mix who recently has been vomiting up his food. He seems to still eat, and still poops regurlarly(and his poops are normal size, shape, color.) It's just that the seems to be vomiting his food up every now and then for the past few days. The vomit looks like chewed up food, there were rather large chunks of carrot in the first two, so we put up the carrots and he is still getting sick. I have also noticed that in the mornings he is waking up with little eye boogers in the corners of his eyes which is something he has never had before. And lastly he seems a little lethargic, not really tired all the time, just a little less active than normal. We have had him since he was 3 months old, and is up to date on all of his shots. This has been going on for 4 days.

He could have food allergies, inflammatory bowel disease, a tracheal collapse, kennel cough (where they cough so hard that they vomit), a partial foreign body in his digestive system, and more.

Of course the best option is to take him to your vet immediately, but if you cannot than try the following temporarily:

Try switching his diet to a hypoallergenic CANNED diet, such as venison and potato, or sweet potato, or some other novel protein source (Novel meaning he has never been exposed to it before).  If he is a picky eater, and you feed him off the table, than still follow the novel protein rule: some meat, fish, fowl, or even tofu that he has never been exposed to before.  

You could also try giving him a probiotic, in his food daily, and 5mg of pepcid.

If his symptoms become worse or you don't see significant improvement quickly, please consult your vet.
