Dog’s blood is similar to human blood and is composed of plasma and blood cells. Plasma is the liquid part of blood, consisting primarily of water, proteins, and other dissolved substances. Blood cells include red blood cells, white blood cells, and platelets. The viscosity of blood depends on the number of red blood cells in the blood and the viscosity of the plasma. The greater the number of red blood cells, the thicker the blood, because the proportion of red blood cells in the blood affects the fluidity of the blood.
The viscosity of plasma can also affect the viscosity of blood, because proteins and other dissolved substances in plasma can Increase blood viscosity. Research shows that dog blood flows more easily than human blood because dog red blood cells are smaller and more regular in shape than human red blood cells. The average diameter of dog red blood cells is 6.5 microns, while the average diameter of human red blood cells is 7.5 microns. In addition, dogs’ plasma also has lower protein content, which also helps reduce blood viscosity. Therefore, dog blood flows more easily than human blood and is less likely to become sticky.
