Their dogs will be well supervised and able to get lots of energy out in our big fenced in yard (nearly an acre), no woods, just grass. I also live across the street from a great park and walking trail. I have a 6 month old puppy and an 11 year old dog so any age would work with them as they are both friendly, though the puppy is much more playful. I would be able to keep dogs separate from them if necessary though, as the house is big enough with 2 extra crates if need be. We have had dogs in our family since I was 8 and I would get more of my own if I could afford it! Thank you for your consideration!
