The heart is located in the thoracic cavity in between the lungs, 60% of it lying to the left of the median plane. The hearts lateral projection extends from rib 3 to 6. Most of the hearts surface is covered by the lungs and in juveniles it is bordered cranially by the thymus. Caudally the heart extends as far as the diaphragm. Variations in position and size exist among individuals depending on species, breed, age, fitness and pathology. Roughly speaking, the heart is responsible for about 0.75% of the bodyweight.
