One thing is for sure, the Jack Russel Terrier is, above all, a very active dog, because it is a working dog. Jack Russel Terriers are dogs that are happiest when you give them something to do. For example, that is why so many Jack Russel Terriers like to go get a ball that you throw. They know that you want them to go get the ball, and thus, you are giving them a task to complete. The only problem is, when you have a Jack Russel Terrier that is in shape, it can run all day long and get the ball for you without ever stopping for a break. The Jack Russel Terrier breed is a breed of dog that people learn to love because of how sweet they are, but this is not a breed for someone that does not like active dogs. This breed wants to go out and run around, and it is going to make you do it as well.
