HMMM. Is it like goosy sounding? sounds like a trachea issue... My Baby Joe does it from time to time and its kinda scarey because she can't breathe until she calms down and gets her breathing back on pattern. She doesnt have to get exerted or anything like that. It just happens. This explains some of the possibiliies.
In certain individual Bulldogs the breathing problems are more pronounced and is known as "Brachiocephalic Syndrome." The first component of this is pinched nostrils (stenotic nares). The openings to the nostrils in these dogs can be no more than slits. Air sounds can frequently be heard with each breath. If you pinch your own nostrils and try to take a deep breath you will experience a feeling of negative pressure down near your larynx or voice box. This negative pressure does several things. It stretches or pulls on the soft palate which is the soft tissue just behind the hard palate (hard roof of the mouth). This condition is known as an elongated soft palate. These dogs will make excessive snorting or snoring noises. Often you can feel strong vibrations when lightly cupping your hand over the underside of their necks. Sometimes too, they will regularly spit up white frothy foam that becomes trapped in their throats. Pinched nostrils and elongated soft palates often go together and can only be helped by surgery. The nostrils can be opened with a "wedge resection" to remove tissue and create a wider opening. This can be done with very little scarring and the sooner it is performed on puppies the better. The soft palate is best shortened using a C02 laser. Lasers cause less swelling, bleeding, and pain allowing the pet to be discharged the same day. The benefits of these surgeries can be dramatic, and are greater in younger animals as compared to a dog that has been having problems for several years.
Two other components of the syndrome are everted laryngeal saccules and a hypoplastic trachea. The saccules are located down within the openings of the trachea or windpipe. The negative pressure formed higher in the airways causes a sac on either side to get sucked out into the airway with every breath. These appear almost as little balloons and further occlude the airflow. These dogs are usually the ones that have had ongoing problems left untreated. They tend to have trouble breathing with the least amount of activity or excitement. The saccules should be excised (cut out) to correct the condition. The last feature of the syndrome known as hypoplastic trachea simply means a very small trachea. Nearly all Bulldogs have a smaller diameter trachea (windpipe) than other dogs.
