There is a particular type of safety collar which is intended for both dogs and cats. Breakaway collars are especially designed to prevent the pet from choking or getting stuck because of their collar. They feature a clever design that releases quickly when a
Limitations of animal running speed Limitations of animal running speed Limitations of animal running speed provides an overview of how various factors determine the maximum running speed. Some terrestrial animals are built for achieving extremely high speeds, such as the cheetah, pronghorn, race horse and greyhound, while humans can train to achieve high sprint speeds. There is no single determinant of maximum running speed: however, certain factors stand out against others and have been investigated in both animals and humans. These factors include: Muscle moment arms, foot morphology, muscle architecture, and muscle fiber type. Each factor contributes to the ground reaction force (GRF) and foot
