The answer to the question about which of the given animals is not actually a dog is letter D or prairie dog. Although they are called dogs, prairie dogs are herbivorous burrowing rodents native to North America – Mexico, United States of America and Canada. There are five species of prairie dogs and these are as follows: black-tailed, white tailed, Utah, Gunnison’s and Mexican prairie dogs.
The reason why these burrowing rodents were called prairie dogs is because of their habitat and warning call which sounded like a dog’s bark. A prairie dog can grow between 12 and 16 inches long and weigh between 1 and 3 pounds. Since they are herbivorous animals, they primarily feed on small seeds, grasses, broadleaf forbs, blue grama, six weeks fescue or buffalo grass.
