I grew up on a farm in minnesota with many animals, dogs being my favorite, I care for animals as if they are children and have a special connection with most, my pups are 4 months old, training, running and exercise is everyday life, I only take non aggressive dogs, size doesn't matter as long as they are gentle to people and other animals, extended stays are fine with enough notice and all pets must be up to date on vaccines and rabies shots, I have no children at home and a fenced in backyard where your dog will be able to play and interact with my pups, I would prefer dogs or our crate trained however I understand with older dogs it is not always necessary
