I have always grown up with dogs! I currently have a 5 year old Boxer, Morgan. She is my mini me and I don't know how I would function on a daily basis without her right there by my side. I have plenty of experience potty training and obedience training. I am not specifically certified in those areas, my expertise come from personal experience. I have had dogs that are very friendly and have also had dogs that aren't so friendly. I am very comfortable with any situation that might arise and all personality types. I know how important each fur baby is to you and will take every stride to make your four legged friend feel right at home while you're away!
