Red wolves are usually under 10 years in the wild. 9) Wolves, like all dogs, are coursers and can maintain a speed for a period of time to chase prey (vs. cats which are stalkers and display fast speeds for short distances). Grey wolves can run up to about 50km/h (30mph). 10) The distance they travel depends again on prey availability, but can travel 15-50km a day (10-30miles).

The greyhound (also spelled grayhound) is a breed of hound dog known for its sleek, well-muscled, and fine-boned racing physique (see dog racing).

The greyhoundâs coat is short, fine-textured, and satiny. The color may be any solid or a combination of colors and patterns.
