Introduction and Hypothesis                                                                             
	In today's world people should know more about their dog’s health and well being.  Respiratory problems such as respiratory cancer can be life threatening for your dog. Cancer starting in a respiratory system is less common than forms of cancer which start in other organs of the body. It is, however, common for tumors to form in the lungs from cancers that have spread from other areas of the body. Of the cancers that occur in the respiratory system, the most common occurs in the nasal sinus passages watching our pets' respiratory rate we can prevent respiratory cancers and illnesses. An experiment that compares dog, kid, and adult respiratory rates can show information on how high or too low is a dangerous respiratory rate. Dogs with flat faces such as pugs, bulldogs, Pekinese, and others are more common to have respiratory problems.
	Respiration can be defined as the process by which an organism takes in oxygen and releases carbon dioxide, one in which the circulating medium of the organism (the blood) comes into contact with air or dissolved gases (Science of everyday things, 2002). The respiratory system includes the mouth and nose, the trachea, and the lungs and smaller airways (bronchi and bronchioles).  Because dogs and cats do not sweat through the skin, the respiratory system also plays an important role in regulation of temperature (Respiratory system of the dog, 2009). The respiratory system of a dog works with the circulatory system to provide oxygen to the body (General physiology of dogs, 2000). 
	If a bulldog does a certain activity for 15 mintues then its respiration will be higher than other dog breeds.
	The results of this experiment will help people keep their dog’s respiration rate down in normal range, not to high and not dangerously low. If someone’s dog has a respiration not in the normal range they will know from my results if they should call a veterinarian for help.
