I have grown up with labrador retrievers and also smaller dogs. I also volunteered at the local Providence Animal Rescue League and walked pitbulls, mutts, etc... I am comfortable with dogs of all sizes! I am a student at Brown University so I have some class during the day but can help in between classes or at night time! I live in a 3 story home that has a yard. There is no fencing but I would take the dog on a leash every time taking the dog out. I also have 12 other housemates who all love dogs and would help out!
