When you think of a “strong” dog, you might picture a massive, muscle-bound giant. But strength in dogs goes far beyond size alone. Is it the Kangal’s bone-crushing bite force, the Rottweiler’s agile power, or the Pit Bull’s tireless endurance that makes them truly strong? The answer isn’t simple—it’s a mix of raw power, instinct, and heart.
Strength in dogs can mean:
- Bite force: Measured in PSI (pounds per square inch), like the Kangal’s 700+ PSI jaw.
- Muscle and agility: Think of a Doberman’s sprint or a Boxer’s punch-like leaps.
- Endurance: The Siberian Husky’s ability to pull sleds for miles in freezing temps.
- Working grit: Breeds like the German Shepherd thrive in police work, using both brains and brawn.
