My dog, 6 months old doxie-pin, was hit by a rock near her nose. It bleeds for about 15mins. She's calm now but I'm afraid if there are any side effects. Her gum didn't bleed though. Help me . Veterinary are far from my town.

Can you see a split or is the blood coming from inside her nose?
If it is just a split keep a very close eye on it, try and keep it dry (although that may be hard if she licks it) distract her with a chew toy or biscuit and see if it bleeds again.

If it is bleeding from inside her nose I would be making a trip to the vet.

Right, and if there is a split or a cut you should rinse with salt water, or water with epsom salts in it.
