Dog Esophagus
The esophagus the gullet, as it is often called is the tube that leaves the pharynx parallel with the windpipe and down which and sometimes up which food passes.
The esophagus is subject to several ills, all of which cause the dog difficulty in swallowing and often in retaining food. Vomiting after eating may be a symptom of such difficulty, as well as of several other maladies. When the esophagus has been burned by acid or caustic, or cut and scratched by any sharp object, the treatment that it needs is rest, so that it can heal. Many lay people, not realizing how long a dog can go without food, try to force it into the cat. This is a great mistake. Milk, broth, and foods that trickle down the gullet with as little irritation as possible are best.
Esophageal worms is a parasitic disease that is not always easily diagnosed. Dogs infested with esophageal worms exhibit the symptoms of cough-in and vomiting. The tumor-like pockets or pouches in the gullet, with many worms, protruding, irritate. Sometimes one or more such tumors may be felt in the gullet behind the windpipe. Considerable damage to blood vessels is believed to result from the migration of the larvae in reaching their resting and living place in the esophagus. Dogs often lose weight, and their frequent gagging and coughing are racking to the dogs and a source of worry to their owners.
The intermediate host for esophageal worms is the dung beetle. Therefore, keeping dogs clean and removing stools frequently will do much to prevent infestation.
Dog Vomit
The Esophagus is a one-way street where the food is pushed down to the intestines in one direction. But several times the direction of the food may reverse due to several reasons. In most cases, it happens when the cardiac sphincter opens and the contents of the small intestines are pushed up toward the mouth through the esophagus.
A dog generally vomits when it suffers from an irritated stomach. This may be due to harmful chemicals, swallowing of nondigestible toys, and heavy production of fluids in the stomach. Vomiting may also take place due to motion sickness. In most cases, vomiting does not occur due to the intake of any harmful or non-digestible materials. The vomiting occurring due to motion sickness is because of the dog’s brain.
The traveling of the food toward the mouth is also known as regurgitation. But there is a difference between vomiting and regurgitation. Before vomiting, you see a facial change in the animal along with the excess level of salivation, the feeling of discomfort, gurgling, winning, and pacing with anxiety. Whereas in regurgitation, you will find that it occurs suddenly and even much to the surprise of the animal itself. In most cases, the regurgitation happens due to excessive contraction of the muscles of the stomach.
The regurgitation takes place due to a lack of swallowing reflex or the malfunctioning of the esophagus. You are recommended to watch keenly the way of eating food of your pet dog. You are advised to take your dog to a vet specialist in case you find the food pieces falling from the sides of the mouth while eating.
