Greyhound Dog
Speed: Around 45 MPH
Greyhound Dogs are potentially known the most for being notable racing dogs that you’ll often see people betting on across the United States. Of course, these dogs are known for being relatively large and even pretty skinny. The skinniest of the Greyhounds tend to be those who are forced to regularly race. However, those that become family pets are in good shape. They might still be skinny as this species is still going to be a bit taller/longer, but that is just how they are.
Many feel that the repeated use in racing, and the training they are put through for it, can cut down on their lifespan. This does make sense, as the same can occur in racehorses and other animals forced into long-term racing. However, it is understandable why the species is put into racing. It is one of the fastest animals on the planet and certainly among the fastest dogs. They tend to regularly reach 27 mph without trying, but they are also able to reach 40 mph. It is not surprising why Greyhounds have been in the world of racing in some form for more than a century.
