* Water temperature: Cold water can significantly impact a wolf's ability to swim effectively.
* Currents: Strong currents make it harder for a wolf to maintain its speed.
* Distance: Wolves can maintain a decent pace for short distances but will likely tire out if they have to swim long distances.
Generally, wolves can swim at speeds up to 5 mph (8 km/h) for short bursts. They can cover relatively long distances in open water if necessary.
It's important to note that this is an average speed, and individual wolves can vary in their swimming ability.
