Ive grown up with dogs almost my entire life. I currently have a 6lb Yorkie who loves to play and is very friendly with other dogs. I currently work from home with a schedule full of flexibility so your baby would never be alone and can get the attention require and need! I live in a huge gated apartment community with plenty of room to walk, run and play! A couple of walks around the complex is great cardio and after that its usually time for a nap.
