I have a 7lb schnauzer and a 150lbs Great Dane. So I have had dog experience with all sizes. My work schedule is mostly early a.m. and always m-f. I work in the medical field which requires me to work a graveyard shift 1 week a month. My dane loves fetch, running, hiking, tug of war, the dog park and other dogs his size. My schnauzer is quite, reserve most of the time. I've been grooming him for 5 years and typically give him the skirt that most have. My dogs are my life , when your dogs are with me they will be as well. Prefer dogs that will be fine with my dogs or other dogs in the case we goto the dog park. My yard is fenced. !! WILL NOT SIT, WATCH OR WALK OVERLY AGGRESSIVE DOGS.
