High maintenance dog breeds, on the contrary, are dogs that require an substantial amount of exercise. Some breeds, like the Border Collie, may need up to two hours per day! These dogs are naturally hyper, and without exercise, can be destructive. These will also be dog breeds that require regular grooming sometimes brushing every day! In some cases, high maintenance dogs may also need frequent baths, as they primarily live outside and often get into dirt (much like my Aussie!).
