I am a big tennis player, I have no problem running/walking long distances with your pups. I have been around and had dogs basically my whole life and will try my best to make their tail wag. I have experiance with sll animals not just dogs (Rabbits, reptiles, amphibians, cats, rodents) I am for the very most part pretty flexible with time but there is some times of the day I can not abandon, should never compromise my time with the dogs. I have one dog, two cats and many reptiles that are in their own room (nothing dangerous) I also have my grandmas house available as well, which is just about 30 seconds walking distance from my house, she owns no animal but will welcome any in her home as well. I have a very large NOT fenced yard but lots of room for playing and exercise!
