Are Jack Russell Terriers very hyper?
Jack Russell Terriers are very energetic dogs, with a high requirement for regular exercise, and a lot of it! They are working dogs, and must have a job to do, whether it be keeping your yard free of rodents (digging is quite common, since they are bred to dig after quarry), chasing a ball, or going for a run or long walk with its owner. Sitting on the couch peacefully all day is not in a Jack Russell’s agenda.
