Dogs can collapse and faint because of vomiting. This is a reflex when vomiting process is stimulating a nerve that slows down the heart rate and dogs may faint as a result of that. The recovery is usually rapid and the dog is back on the feet within seconds. If that what has happened to Aries, you can monitor him at home for the next 15-30 min. If it was only the reflex, he should be back to normal by now. If he is still staggering or looking confused please take him to your local vets as an emergency. Vomiting and balance problem can be related to ear infections, intoxication or even neurological diseases.
