Amazing video of a grey wolf doing the doggie paddle across Oba Lake in Ontario, Canada.
Youtube video uploader spotted him early in the morning and got the boat within 20 feet before he hit shore and disappeared into the woods.
Wolves walk, trot, lope, or gallop. Their legs are long, and they walk at about 4 miles (6.4 kilometers) per hour, but can reach speeds of 35 mph during a chase. Their usual mode of travel is to trot, which they do at various speeds, generally between 8 to 10 miles (12.8 to 16 kilometers) per hour.
Wolves do not run at full speed until they get close to their prey as possible. At that point, they make a high-speed chase to test the animal.
Wolves can keep up this pace for hours on end and have been known to cover 60 miles (96 kilometers) in a single night. They have been clocked at speeds of over 40 miles (64 kilometers) per hour for a distance of several miles.
The wolf is very comfortable in the water, and does not hesitate to wade through icy streams or swim across short stretches of lake. In summer, wolves often bathe in streams to keep cool, and they will readily follow prey into water.
