Most passive mobs don't wander more than about 32 blocks from the player. This is intended per MC-47533. However frogs are an exception to this rule. This causes several issues. You can test this by going into spectator mode near a frog and a cow. Notice the frog moves but the cow doesn't.
Note: If you use /summon to test this (or probably any method of spawning), the game allows the mob to move for a little bit before the rule applies, so like cows that were just spawned will move for a second before staying still
