    Air under Dog's skin
    dogbutton posted:
    My dog who is a mix between a beagle and a lab and is 8 yrs old has air under her skin beginning around the middle of her stomach and going into both back legs. I have taken her to the Emergency Dog Hospital who was not able to diagnose her problem, saying, I have never seen this before. I next took her to her own vet who xrayed her and again could not find the problem. Again I have never seen this before. She is on antibiotics given to her once from the emergency hospital and again when we went to our vet. I am almost at my wits end. This dog lives a very pampered life. She is a inside dog who sleeps with either me or my daughter. She never goes outside except to take care of her business. There has been no trauma, no puncture wounds, bits etc. Can someone help me find out what is happening to her.
    Sandy Willis, DVM, DACVIM responded:
    Hi Dogbutton,

    What you are describing is subcutaneous emphysema, or air under the skin. This is usually caused by damage to the trachea in the neck or some trauma to the chest, lungs, etc. Generally it occurs around the fore legs not the back. Xrays of the chest and perhaps neck would be a good idea. Perhaps this is spontaneous without a cause but air generally comes from the airways, so I would have your veterinarian look there.

    Let us know what you find out.

    Dr. Sandy
