How Are Humans Connected To Jack Russell Terriers?
Jack Russell Terriers are important to us because they are good hunting animals and are great companions. Most hunters would love to have a dog like that ( because they are bred to hunt Foxes for food). So if Jack Russell Terriers became extinct then we wouldn't have dogs that have those hunting skills, and the population of Foxes could over flow and a lot of things would go wrong in the wild just because one species became extinct!
