I just got a little pug and ive heard that there eyes will pop out of there head.
It is scary to think about, but an accident or a hit on the head can cause the eyeball to literally pop out of its socket, a condition called prolapsed eyeball, or proptosis. While this can occur in any breed of dog or cat, pets with bulgier eyes, like pugs, Pekingese, and Persians, are at greater risk simply because their eyes stick out farther to begin with.
This prolapsed eyeball is obviously quite serious. Once the eyeball pops out, the eyelid clamps down behind it, trapping the eyeball outside the socket and possibly cutting off the supply of blood. It is essential to get the eye back into its socket within about 10 minutes in order to preserve your pet's sight. If you can't get to your vet's office immediately, it is possible to replace the eye yourself, but it is best to get to a veterinarian immediately.
