human breathing is some time fast from first nostril and second nostril from slow. There after some time changing, slow breathing from first nostril and fast breathing from second nostril.
YOU ACTUALLY ONLY BREATHE OUT OF ONE NOSTRIL AT A TIME! TRY THIS OUT - PLACE THE BACK OF YOUR HAND UNDER BOTH NOSTRILS AND BLOW GENTLY THOUGH YOUR NOSE - YOU WILL ONLY FEEL THE BREATH FROM ONE NOSTRIL - TRY IT AGAIN ABOUT 30 MINUTES LATER AND IT WILL HAVE CHANGED TO THE OTHER NOSTRIL!
I would say take him/her to the vet. they will tell you if its common or not.
Uninaribus means having one nostril (i.e. aliens or monsters have one nostril).
I had a similar situation happen to me, and my nose didnt grow right through development. The septum (the middle wall in your nose) grew to the right side, so one nostril's passage is blocked. Your going to have to get reconstructive surgery to straighten the septum, and possibly remove some flesh material from within the nasal cavity in order to open your nasal passages.
What causes you to breath through only one hole from your nose is the fact that the other hole is blocked by mucus, or "boogers" if the mucus has dried up. If this not the case then you should ask your doctor. Sometimes this is normal. It may be the body's way to get you to turn over in your sleep and prevent bed sores. What happens is that the turbinates in your sinuses swell.
I didn't when i had one
Either nostril can become blocked by mucus or swelling of the nasal lining. In some cases, the pathway to the nasal turbinates (rear passages) can become closed and result in only one nostril bringing air in. You could try saline spray (non-irritating) or see your doctor about using decongestants or other treatments to enable both sides of the nose to take in air. Rarely, this could require medication to reduce thickening of the turbinate walls.
