I have lived with dogs my entire life and am very comfortable around them. I have babysat for families who have dogs in their household and had to care for them as well. Im attending school in Seattle and during the day I am able to run to your house and let them out and take them on short walks between classes. I own two dogs myself and they love to play with other dogs. If I had one stay the night they would all get along and play 24/7. If you are not comfortable with this I would make arrangements for dogs to be in different areas of the house making sure your dogs is cared for just as well as my own.
